Boron Carbide B4C Supplier

Boron Carbide B4C Supplier

Boron carbide have good performance in the grinding of gem and polishing of epitaxial wafers.

Due to the high strength and hardness of the gem it has brought great difficulties to the processing enterprises. From the point of view of materials and grinding academia, the best materials for processing and grinding gem crystals are synthetic diamond, boron carbide, and silicon dioxide. Due to the excessive hardness of artificial diamond, the surface of the gem will be scratched when grinding, which will affect the light transmittance of the wafer, and it is expensive. However, insufficient hardness of silica and poor grinding force are time-consuming and labor-intensive in the grinding process. Therefore, boron carbide abrasives are ideal materials for processing and grinding gem crystals.

Boron carbide, also known as black diamond, is an inorganic substance with a chemical formula of B4C, usually gray-black micropowder. It is one of the three hardest materials known (second only to diamond and cubic boron nitride). It is used in gem grinding polishing tankarmor, bulletproof vests and many industrial applications. Its Mohs hardness is about 9.6

boron Carbide is produced by high temperature smelting boric aid and carbon materails in electric furnaces.
