Hexagonal Black Silicon Carbide Powder for Stone Polishing - Hv3100-3280 Hardness, F12-P2500 Grit Sizes
Hexagonal polishing and lapping grade black silicon carbide micron powder engineered specifically for the stone industry, featuring exceptional micro hardness of Hv3100-3280.
Black silicon carbide is primarily synthetic due to the rarity of natural moissanite. It serves as a high-performance abrasive and has applications in semiconductor technology and diamond simulation. Manufacturing involves combining silica sand and carbon in Acheson graphite electric resistance furnaces at temperatures ranging from 1,600°C to 2,500°C.
