Black silicon carbide grit F24# 36# for grinding wheel
- Description for black silicon carbide:
Black silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips and other raw materials in the resistance furnace by high temperature smelting, smelted by high temperature in the resistor furnace, which is black opaque body, hexagonal crystals, and Mo’s hardness is the hardness of Mo’s hardness as 9.15. It is second only to diamond and boron carbide, which is crispy and sharp and has certain conductivity.

- Usage for black silicon carbide
1. Abrasive: It is mainly used for making sand wheels, sandpaper, oil stones, grinding heads, grinding pastes and photovoltaic products in single crystal silicon, polysilicon and surface grinding, polishing, etc.
2. High -grade refractory materials: It can be used as metallurgical oxygen and high -temperature resistance, and make high -temperature furnace kiln components, support parts, etc. 3. Functional ceramics: not only can reduce the capacity of kiln furniture, but also improves the quality of kiln products and shorten the cycle. It is an indirect material for ceramic glazed baking sintering. High temperature non -oxide ceramics and reaction sintering ceramics.
4. Nonferrous metals: The steel industry and metallurgical mining industry are all applied.
