1, silicon nitride bonded silicon carbide products, hard texture, Mohs hardness of about 9, in the non-metallic materials are hard materials, second only to diamond.
2, silicon nitride bonded silicon carbide products at room temperature high strength, in the 1200-1400 °C high temperature, almost the same time and the same temperature and hardness at room temperature. With the use of different atmospheres, the maximum safe use temperature can reach 1650-1750 °C.
3, the thermal expansion coefficient is small, compared to silicon carbide and other products with high thermal conductivity, easy to produce thermal stress, with good thermal shock stability, long service life. High temperature resistance to creep, corrosion resistance, extremely cold and hot, anti-oxidation, easy to make products with high dimensional accuracy and meet the requirements.
4. The products are widely used in various industries such as iron and steel, non-ferrous metals, chemical building materials, etc., saving energy, protecting the environment, and reducing costs.
