1) Silicon nitride bonded silicon carbide plate with high hardness, the Mohs hardness is about 9, in non-metallic materials belong to high hardness materials, its hardness is second only to diamond.
2)Silicon nitride bonded silicon carbide plate has high strength at room temperature, and almost maintains the same strength and hardness at room temperature at 1200 ~ 1400℃. With the different atmosphere, the maximum safe use temperature can reach 1650 ~ 1750℃.
3)The thermal expansion coefficient of silicon nitride boned silicon carbide plate is small, the thermal conductivity is high compared with silicon carbide brick, it is not easy to produce thermal stress, has good thermal shock stability, and long service life. High temperature creep resistance, corrosion resistance, extreme cold and heat resistance, oxidation resistance, easy to make high dimensional precision meet the requirements of the brick.
