Silicon nitride combined with silicon carbide thermocouple protection tube and its application

The introduction of silicon nitride combined with silicon carbide thermocouple protection tube and its application is as follows:
Silicon nitride bonded silicon carbide material is a new type of material, with main products including silicon nitride bonded silicon carbide radiation tubes, silicon nitride bonded silicon carbide bricks, silicon nitride bonded silicon carbide plates, etc. It is widely used in various industries such as steel, non-ferrous metals, chemical building materials, and has many advantages such as energy conservation, environmental protection, high temperature resistance, and corrosion resistance.
1. Silicon nitride combined with silicon carbide products has a hard texture, with a Mohs hardness of about 9. Among non-metallic materials, it belongs to the hardness category, second only to diamond.
2. The strength of silicon nitride combined with silicon carbide products at room temperature is high, and they maintain almost the same strength and hardness as at room temperature at temperatures ranging from 1200 to 1400 ℃. With different usage atmospheres, the maximum safe usage temperature can reach 1650-1750 ℃.
3. The coefficient of thermal expansion is small. Compared with silicon carbide and other products, it has high thermal conductivity and is not easy to generate thermal stress. It 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 products with high dimensional accuracy that meet the requirements.
4. The products are widely used in various industries such as steel, non-ferrous metals, chemical building materials, etc., saving energy, environmental protection, and reducing costs.
The company undertakes customized processing of various types of silicon nitride composite and silicon carbide thermocouple protection tubes all year round, used for the protection of temperature measuring thermocouples in special media and extreme working conditions. It has the characteristics of high temperature resistance, wear resistance, corrosion resistance, and prolongs the service life of the thermocouple.
