Black silicon carbide 98.5% SIC is made of quartz sand, petroleum coke and high-quality silica as the main raw materials, and is smelted by electric furnace at high temperature. SiC 98.5% lapping black silicon carbide can used for refractory purpose or in electronic industry. Lapping black silicon carbide also has the resistivity necessary to perform as a semiconductor material.Because of these properties, Black Silicon Carbide HS Code 28492000, CAS No. 409-21-2, is used in a wide range of applications and industries.
We are professional black silicon carbide manufacturer for customers in different industries and countries according to FEPA, JIS, GB, ISO, ANSI & P standard. 0-1mm, 1-3, 3-5mm etc. for refractoriness, FEPA F sizes for bonded abrasives aluminum oxide tools, FEPA P sizes for coated abrasives silicon carbide products.
