Synthesis of advanced ceramics and intermetallics from organometallic/polymeric precursors
Abstract Titanium-containing powders and fibers were synthesized via the modification of polyacrylonitrile (PAN) by titanium dialkylamides and titanium tetrachloride. Pyrolysis of the chemically modified PAN in reactive/inert atmospheres produced materials containing Ti(C, O). The mixed-metal organometallic cluster iron-tricobalt-hydrido-dodecarbonyl was also synthesized and on pyrolysis yielded Fe-Co intermetallics. These materials were characterized by SEM-EDAX, ESCA, Auger and atomic absorption spectroscopy.
