Carbure de silicium is an important raw material for refractory materials. Il est souvent utilisé pour fabriquer des matériaux réfractaires, comme les briques en carbure de silicium, éléments moulés en carbure de silicium, carbure de silicium combiné à des briques en nitrure de silicium, etc.. La raison pour laquelle il peut être utilisé comme matière première pour les matériaux réfractaires est principalement due à ses avantages évidents..

1. Point de fusion élevé: The melting point of silicon carbide is as high as about 2700℃, which makes it possible for refractory materials to have high refractoriness when used as refractory materials. Generally, the refractoriness of refractory materials made of silicon carbide can reach about 1790℃, which can keep the structure of refractory materials stable at high temperatures.

2. Good chemical stability: Silicon carbide has good corrosion resistance and can have strong resistance to acid, alkali and salt solutions, and can resist corrosion in high temperature environments;

3. Conductivité thermique: The thermal conductivity of silicon carbide is about 80-200W/(m·K). This feature helps refractory materials to quickly transfer heat at high temperatures and improve thermal efficiency.

4. Bonne résistance à l'usure: Silicon carbide has very good wear resistance. It can resist the erosion and wear of materials very well, so it is widely used in some parts with severe wear. 5. Haute résistance: Silicon carbide has high strength and can maintain the stability of the kiln in a high temperature environment.

Through the characteristics of silicon carbide, we can roughly understand the role of silicon carbide in refractory materials. It can keep the refractory materials at a high refractory performance. En même temps, it has good resistance to chemical erosion. En même temps, due to its excellent wear resistance, it can resist the erosion and wear of materials in some key parts with severe wear. Not only that, due to the high thermal conductivity of silicon carbide, it can improve the thermal efficiency of the kiln and reduce energy consumption.
