The development of the technology of silica - mullite brick 1

As a kind of firing conversion, the main mineral composition of silicon mullite brick is silicon carbide (SIC) and mullite (3Al203，2SiO2), which is based on the application of traditional high alumina brick technology through the improvement of infiltration silicon carbide technology. Therefore, compared with high alumina brick, it not only has high strength, but also has the wear resistance and corrosion resistance of silicon carbide and high temperature resistance of mullite. Adding silicon carbide to brick products can form a protective film on its surface, so that the durability of special products can be improved and further oxidation of silicon carbide can be effectively prevented; In the high temperature environment, silicon carbide can react with bauxite clinker to form mullite, which can improve the strength and density of products, and then effectively improve the corrosion resistance, wear resistance and thermal shock stability of products.
