info@rsrefractories.comSilicon Carbide is hexagonal crystal, with stable chemical properties, high thermal conductivity, small thermal expansion coefficient, good wear resistance, Mohs hardness of 9.5. It has black and green two basic varieties. Black silicon carbide has good toughness, it is widely used in glass industry, ceramic industry, stone industry, refractory industry, iron industry, non-ferrous industry and so on. Green silicon carbide has good self-sharpening, and is mostly used for processing hard alloy, titanium alloy and optical glass, and also for honing cylinder liner and accurate grinding HSS tool.

Application of Black Silicon Carbide Powder:
1. Abrasives: mainly used for grinding wheel, sandpaper, oilstone, grinding head, grinding paste, monocrystalline silicon, polycrystalline silicon in photovoltaic products and surface grinding and polishing of various devices.
2. High grade refractory: it can be used as metallurgical deoxidizer and high temperature resistant material to make high temperature furnace components, supporting parts, etc.
3. Functional ceramics: it can not only reduce the capacity of kiln tools, but also improve the quality of kiln products and shorten the cycle. It is an ideal indirect material for baking and sintering of ceramic glaze, high temperature non oxide ceramics and reaction sintering ceramics.
4. Non ferrous metals: Iron and steel industry, metallurgy and mineral processing industry, have been applied.
