First of all, silica is the main component of quartz ceramics. Secondly, as an additive, it can also effectively enhance the performance of ceramics. For example, using silica instead of nano Al2O3 to add to 95 porcelain, it can not only play the role of nano particles, but also the second phase particles, not only improve the strength and toughness of the ceramic material, but also increase the hardness and hardness of the material. The elastic modulus and other properties are more ideal than adding Al2O3.


The use of silica to composite the ceramic substrate not only improves the compactness, toughness and smoothness of the substrate, but also greatly reduces the sintering temperature. In addition, the application effect of silicon dioxide in ceramic products such as ceramic filters and corundum balls is also very significant.
