Using fumed silica instead of nano-Al2O3 to add to 95 porcelain can not only play the role of nanoparticles, but also the second phase particles, which not only improves the strength and toughness of ceramic materials, but also improves the hardness and elasticity of materials. Modulus and other properties, its effect is more ideal than adding Al2O3. Using fumed silica to composite ceramic substrates not only improves the compactness, toughness and smoothness of the substrates, but also greatly reduces the sintering temperature. In addition, the application effect of fumed silica in ceramic filters, corundum balls and other ceramic products is also very significant.

        According to the editor of China Powder Network, it can also be used as a carrier to load Ti, Ag or Cu ions into ceramic materials by using its porosity, which can play an antibacterial effect, thereby preparing antibacterial ceramic sanitary ware.
