Black silicon carbide powder is the same as green silicon carbide powder, the main ingredient is silicon carbide (SiC), but a small amount of iron is added during its production process, thus giving it a black color. Black silicon carbide is slightly softer than green silicon carbide, slightly less hard and brittle, but has good toughness and conductivity.
black silicon carbide powder characteristics
1. Higher hardness: Black silicon carbide has a Mohs hardness of about 9.2, which is slightly lower than that of green silicon carbide, but it is still an extremely hard material.
2. High toughness: Compared with green silicon carbide, black silicon carbide has higher toughness, suitable for some demanding grinding and cutting processes.
3. Conductivity: Black silicon carbide has good conductivity, so it is used in some conductive materials or electric heating elements.
4. Good abrasion resistance: Black silicon carbide is excellent in abrasion and corrosion resistance, especially suitable for use in harsh environments.
black silicon carbide applications
1. Abrasives: Black silicon carbide is commonly used in the manufacture of grinding wheels, sandpaper, abrasive paste, etc. It is mainly used in the processing of hard materials such as metal, stone, glass, etc., especially those with high toughness requirements.
2. Refractories: it is commonly used in the manufacture of high-temperature furnace refractories and kiln furniture, with good resistance to high temperature and thermal shock resistance.
3. Metallurgy: In the metallurgical industry, black silicon carbide is used as a deoxidizer and refractory reinforcement in the smelting process to enhance the quality of metals.
4. Conductive materials: Due to its conductivity, black silicon carbide is commonly used in electric heating elements and other high-temperature conductive devices.
5. Construction and ceramics industry: It can be used to produce wear-resistant coatings, refractory bricks and high-performance ceramics.
Compared with Green Silicon Carbide, Black Silicon Carbide is slightly less hard but more ductile, and its electrical conductivity is more prominent, thus making it more suitable for some special industrial needs.
