described herein is a continuous or segmented , low cost but high - precision fabrication method for the purpose of making thick , “ green ” ceramic tapes intended as a building block for making complex , fully ceramic components and devices for electronic -, lab - on - chip -, and sensing applications . these devices are always realized by the sintering of the “ green ”, processed and mounted , ceramic building block . for a more complete understanding of the technology upon which the inventive tape and method is based , the following aspects of ceramic components fabrication are elaborated below : fig1 shows a flow diagram representation of the continuous , in - line fabrication method . the fabrication can also be performed in an off - line process with separated fabrication steps , not linked into a line . the specific steps are however necessary steps in the process , and can be represented either by a single , physical processing unit or two or more physical units in combination in order to meet the objectives of the described step . the essential steps in the fabrication method are the paste mixing and homogenization , the dimensioning , and the structuring . the numbers refer to those of fig1 : paste mixing and homogenization ( 1 ). the “ green ” feed material is first mixed and homogenized . this process can preferably take place in two steps , first by the use of a high - speed intensive rotary mixer , ensuring a homogeneous mix of the ingredients and at the same time granulation of the homogenous material . this step is preferably combined with an extruder . the extruder will further improve the paste homogeneity due to an enhanced shear force during processing . this should however not exclude any other efficient method for mixing and homogenization . the paste delivered from this step is preferably a sheet material ready for the following step . dimensioning and structuring ( 2 ). the dimensioning and structuring is taking place in the extruder and a roll forming or calendering unit . by using a tubular / circular exit die with a splitting device at the outlet of the extruder , one creates a sheet product with constant thickness , thus avoiding the difficulties obtained with a linear slit that has to be shaped as a “ dog - bone ” ( due to die friction . the “ dog - bone ” shaped , linear slit will challenge the sheet forming during the rolling / calendering , which may cause an uneven , final sheet thickness or edge cracking ). the final accurate dimensioning will then take place in the roll / calender . the number of the roll sets ( one or multiple sets ) can be chosen for the specific application or product . this will guarantee for the surface quality and the exact dimensioning of the “ green ” product . also by structuring one or both of the rolls , a pattern or structure can be printed or embossed into the “ green ” product . this covers both a partial imprint and embossing as e . g . when fins for enhanced heat transfer are wanted , and a partial perforation of the product for easy removal of single components . the shaping and structuring of the paste / component could in principle also be done at the extruder . however , for ceramic pastes the surface quality and the dimensional accuracy would then not be as good as after the rolling / calendering . thick , “ green ” tapes and components made by the disclosed method should therefore be rolled / calendered for achieving high quality , dimensional accuracy , and structure ( if needed ). if wanted , different ceramic materials can be laminated in the rolling / calendering step , providing special properties for the component ; compositional , chemical or structural . these laminated structures will appear as monolithic structures , with isotropic and homogeneous properties within each layer . the drying ( 3 ) of the “ green ” tapes can take place directly after the roll shaping / calendering , and is preferably an in - line , continuous process step . air , dry or wet , at room temperature or increased temperature may preferably be used as drying medium , conventionally heated or hf heated . alternatively the drying can take place after the cutting as a part of the sintering process . the cutting ( 4 ) is a part of the structuring and can take place before or after the drying stage . the single components can be ready cut , but a more cost effective solution is to cut multi - component sheets , so that a large number of single components are joined by a perforated joint , ready to chip off when needed . the handling and further processing ( e . g . printing of electric connections ) will then be facilitated . the cutting is organized in - line , as a continuous process step , where the products are cut to sizes or multi - component sheets that suit the sintering step . if necessary , sheets can also be punched or cut to size in an external process step before entering the sintering furnace . the product is delivered as single or continuous sheets or blocks after the cutting step . the sintering ( 5 ) is the first of the post processing steps . the sintering is preferably continuous , but may alternatively be a batch type process , depending on the making of the final products with the ceramic tapes . the post processing , in addition to the sintering , typically includes printing of the outer electric pattern , and the final mounting of the finished component . the described preferred fabrication method utilizes a feed material in the form of a highly viscous paste with ceramic powder , binder , plasticizer , dispersant , and solvent . depending on the quality of the ceramic powder material to be used , its size , shape , and properties , the pastes typically comprise : 60 - 90 wt % ceramic powder , 2 - 15 wt % binder , 0 - 10 wt % plasticiser , 0 - 5 wt % dispersant , and 0 - 30 wt % solvent . by “ highly viscous paste ” as used herein is understood a paste having a viscosity sufficient to maintain its physical shape during the process when not exposed to external forces ( other than gravity ). all ceramic materials can be used for making the thick tapes , as e . g . the oxide based ltcc ( low temperature cofired ceramics ), zirconia , silica or any glass material , alumina , titania and titanates ; the nitride based aluminium nitride , silicon nitride ; the carbide based silicon carbide ; the boron based titanium diboride , or a combination of two or more of the materials . the ceramic material can be present in the material recipe as particles / particulates , granules , fibres , platelets , or any other shape . the material recipes can cover tapes intended as dense or porous final , sintered products . other inorganic material elements may be added to the ceramic powder , in order to create special properties or a final ( sintered ) bonding material phase guaranteeing a proper mechanical bonding between the ceramic particles . these material additives often include , but are not limited to , other oxides , based upon oxides from calcium , cerium , lanthanum , silicon , strontium , titanium , and / or zirconium , and derivatives , extensions , mixes , and / or combinations of these . the binder material can be applied either together with a solvent , or solvent free . the solvent can be either an organic solvent or water . solvent free binders are usually waxes , gums , and thermoplastic materials that usually demands elevated temperatures during the processing for good mixing and processing . binders with solvents are generally organic or inorganic materials that can be dissolved in a specific solvent or water , which increases in viscosity when the solvent is removed . extrusion and calendering generally need pastes with a low amount of binder and solvent . the thick , “ green ” ceramic tapes produced by the proposed fabrication method are fabricated with methylcellulose ( or derivatives of this ) binders and water as solvent , enabling production at room temperature ( 10 - 35 ° c . ), which again reduces energy consumption during processing and keeps a solvent - free working environment . the thick , “ green ” ceramic tapes produced by the proposed fabrication method are homogeneous with a mainly uniform and isotropic structure . layered materials will be ideally uniform and homogeneous within each layer . the tape thickness may easily be varied between 0 . 3 mm and 30 mm , however there are no strict thickness limitations to the method . the thick , “ green ” ceramic tapes can be delivered as a flat sheet or as a structured sheet with e . g . grooves or surface pattern on one or both sides . these patterns are easily achieved in the calender / roll with profiled ( grooved ) rolls . fig2 shows an example with a thick , “ green ” ceramic tape , structured on one side . the grooves are here 1 × 1 mm in cross - section , spaced apart with 1 mm distance . the dimensions , the structure , and the repeatability of the pattern can however be selected for the specific application . this structure is made in the calendering step of the process . fig3 shows a 1 mm thick silica tape , which has been punched with square holes . the details of the punched holes can be seen in fig4 . the precision of the punching process is good . the punching is performed in a post processing step . fig5 shows a 1 mm silica tape being deep drawn . the deep drawing is performed in a post processing step . this shows the machinability of the produced silica tapes . fig6 shows a 1 mm thick zirconia tape , which has been punched with circular holes . the precision of the punching process is good , and shows the machinability of the produced zirconia . the punching is performed in a post processing step . fig7 shows 1 mm thick , “ green ”, produced and cut ltcc tapes . fig8 shows ltcc material that has been used for extrusion only in order to make rods . this was done in order to check the machinability of the ltcc material . a hole of diameter 1 mm is drilled through the 3 mm rod without problems . the machinability of the produced ltcc material was good . fig9 shows 12 . 5 mm thick , “ green ”, produced and cut alumina tapes . the finishing of the components takes place after the calendering , and will generally include sizing of the tape sheets and any printing ( e . g . : screen printing , ink jet printing , rotogravure printing or stencil printing ) of any additional functional pattern , before the qc , packing and shipping , or final sintering . the thick , “ green ” ceramic tapes are intended for the oem markets in the electronic and sensor / fluidic component sector . different inventive thick , “ green ” ceramic tapes have been fabricated and machined according to the inventive method , as described more thoroughly in the following illustrative examples . “ green ” alumina thick tape fabricated according to the invention is shown in fig2 . this is structured on one side , with grooves of 1 × 1 mm cross - section spaced 1 mm apart . the alumina thick tape was fabricated according to the invented method with a paste consisting of : 81 . 6 wt % ceramic powder , 3 . 5 wt % binder , 1 . 9 wt % plasticiser , 0 . 05 wt % dispersant , and 13 . 0 wt % water . “ green ” silica thick tape fabricated according to the invention is shown in fig3 and 4 . the tape has a thickness of 1 mm , and has been punched with square holes with side length 0 . 45 mm . the silica thick tape was fabricated according to the disclosed method with a paste consisting of : 61 . 6 wt % silica , 4 . 5 wt % binder , 1 . 7 wt % plasticiser , and 32 . 2 wt % water . “ green ” silica thick tape fabricated as in example 2 , is shown in fig5 . the silica thick tape has been successfully deep drawn . “ green ” zirconia thick tape fabricated according to the disclosed method is shown in fig6 . the tape has a thickness of 1 mm , and has been punched with circular holes with diameter 1 mm . the zirconia thick tape was fabricated according to the disclosed method with a paste consisting of : 75 . 9 wt % zirconia , 6 . 8 wt % binder , 1 . 6 wt % plasticiser , 0 . 5 wt % dispersant , and 15 . 2 wt % water . “ green ” ltcc thick tape fabricated according to the disclosed method is shown in fig7 . the ltcc material was the hereaus material 503k06 . the tape has a thickness of 1 mm , and has been punched with circular holes of diameter 1 mm . the thick tape was fabricated according to the invented method with a paste consisting of : 65 wt % ltcc , 7 wt % binder , 3 wt % plasticiser , and 25 wt % water . “ green ” ltcc material , as in example 5 , has been used for extrusion only in order to make rods , see fig8 . this was done in order to check the machinability of the ltcc material . a hole of diameter 1 mm is drilled through the 3 mm rod without problems . “ green ” alumina tape , 12 . 5 mm thickness , produced in the same manner described in example 1 is shown in fig9 . the product is a standard , produced thickness , showing the flexibility of the invented fabrication method . in its simplest form the fabrication method according to the present invention may be described as a method for fabrication of thick , “ green ”, ceramic tapes intended as building blocks for making complex , ceramic components and devices , comprising in sequence : i ) mixing a ceramic “ green ” paste , and ii ) dimensioning and optionally structuring the ceramic paste , in which the step of dimensioning and structuring the ceramic paste is made in two steps , the first step being extrusion of the paste , and the second being calendering of the extruded paste , allowing fabrication of thick , “ green ”, ceramic tape components .
