Description

SiSiC bricks are made by using reactive Si liquid or alloy to infiltrate into porous ceramics containing C through capillary force and react in situ to produce SiC to complete the densification process. SiSiC bricks have all the advantages of SiC ceramics, with high strength, high hardness, good thermal shock resistance, good wear resistance and corrosion resistance, high thermal conductivity, low coefficient of linear expansion, and excellent oxidation resistance, which is a High-tech ceramic material with excellent performance. Compared with R-SiC, it has excellent oxidation resistance, load-bearing capacity and volume stability.

  Application:

Silicon carbide bricks are advanced refractory materials made of SiC as the main raw material, with a series of excellent properties such as high strength at normal temperature and high temperature, large thermal conductivity, small thermal expansion coefficient, good thermal shock resistance, excellent high temperature wear resistance, and strong resistance to chemical erosion, etc. Widely used in steel industry, non-ferrous metallurgy, petrochemical industry, electric power, ceramics and aerospace fields.

Silicon carbide bricks can be divided into oxide bonded (clay bonded, mullite bonded, SiO2 bonded), nitride bonded (Si3N4 bonded, Sialon bonded), self bonded (β-SiC bonded and recrystallized silicon carbide) and silicon infiltration reaction sintered silicon carbide bricks according to the bonding method.
