Heat Resistant Refractory Products Silicon Nitride Bonded Silicon
Carbide Brick Hook
Introduction
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.
Performance
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.
Application:
The products are widely used in steel, nonferrous metals, chemical
building materials and other industries, energy saving,
environmental protection and reduce costs.
