Black silicon carbide sand 60#-150# for silicon carbon rod
Silicon carbon rods are commonly used high-temperature electric heating components. They are usually made of silicon carbide and other materials by blanking and firing. Black silicon carbide sand is its main raw material. It has the following significant advantages:
1. High hardness. The Mohs hardness of silicon carbide is as high as 9.2 with excellent wear resistance. Thus, SiC is suitable for high wear environments.
2. High melting point. The melting point of silicon carbide is about 2700°C. So it can still remain stable at high temperatures, suitable for high temperature applications.
3. Excellent thermal stability. The physical and chemical properties are stable at high temperatures, not easy to deform or decompose. Therefore, SiC grain works well in high temperature environments.
4. Good thermal conductivity. Excellent thermal conductivity helps to quickly dissipate heat and prevent local overheating.
5. Excellent chemical stability. Acid and alkali corrosion resistance, suitable for strong corrosive environments.
6. High mechanical strength. High mechanical strength, good compression and bending resistance, suitable for high stress environment.
7. Good electrical properties. It has a certain electrical conductivity and is suitable for applications that require electrical conductivity.
8. Low thermal expansion coefficient. Low thermal expansion coefficient, stable size at high temperature, reducing damage caused by thermal stress.
9. Excellent oxidation resistance. Silicon carbide has good oxidation resistance at high temperature and extends service life.
Black silicon carbide 60 mesh-150 mesh is usually selected as the raw material for silicon carbon rods. Due to its high hardness, high melting point, excellent thermal stability, good thermal conductivity, chemical stability, high mechanical strength, good electrical properties, low thermal expansion coefficient and oxidation resistance, it has become an ideal choice for high temperature, high wear and strong corrosion environment.
