Heat Resistant Refractory Products Silicon Nitride Bonded Silicon Carbide Brick Hook
Silicon nitride bonded silicon carbide material is a new type of high-grade refractory material, the main products are silicon nitride combined with silicon carbide radiation tube, silicon nitride combined with silicon carbide brick.
Silicon nitride combined with silicon carbide Performance :
1, silicon nitride bonded silicon carbide products, hard texture, Mohs hardness of about 9, in non-metallic materials are hardness materials, second only to the diamond.
2, silicon nitride bonded silicon carbide products at room temperature high strength, in the 1200-1400 ℃ high temperature, almost the same time and room temperature to maintain the strength and hardness. With the use of different atmosphere, the maximum safe use of the temperature can reach 1650-1750 ℃.
3, thermal expansion coefficient is small, compared to silicon carbide and other products, high thermal conductivity, not easy to produce thermal stress, with good thermal shock stability, long service life. High temperature resisting ability, corrosion resistance, resistance to extreme cold, anti-oxidation, easy to produce high dimensional accuracy to meet the requirements of the products.
The products are widely used in steel, nonferrous metals, chemical building materials and other industries, energy saving, environmental protection and reduce costs.
