Nano-Si can be produced by two ways. One method is based on Magnesiothermic Reduction of Rice Husks, as a by-product from the production of rice that is abundant all over the world. This method is able to produce nano-Si with the exact ability to revert and conductivity as conventional silicon.
Nano-Si is a high-performance material with a high surface activity along with high purity. It is also non-toxic and has high surface area. It is used in high power lighting sources. These devices utilize a small amount of nano-Si in order to create light. Nano-Si particles are tiny, less than 5 nanometers in size.
Silicon nanoparticles can also be produced through chemical vapor deposition or grinding mechanically. The nanoparticles of silicon are also manufactured by plasma evaporation as well as condensation. In the western world nano-Si is made industrially through specialized companies. Some of these companies include Chemicalbook from Japan, DuPont of the United States, H.C. Stark of Germany and Tekner out of Canada. These companies make nano-Si with high purity and different particle sizes.
Nano-Si is an interconnected network of crystalline silicon nanoparticles. The network is visible with HRTEM. The nanoparticles are 8-10 nm in diameter. However, larger particles are distributed in the smallest amount. The large porosity of nanosilicon powder is due to the precise etching and etching of particles. Also, it contains NaCl, a solvent that stops localized melting of the material.
Nano silica fume , a mineral having a larger surface. It has greater amorphous silica concentration than quartz powder, which influences both chemical and physical Reactivity. It has a greater pozzolanic activity indicator than quartz which is 330 times higher than that of the pozzolan. This is due to the differences in the proportion and amount of aluminum oxide present within silica fume and quartz.
Nano silica fume is utilized to enhance the mechanical properties of concrete. It can increase the strength of concrete via thickening the pas
