JEWELLERY POLISHING MEDIA SILICON CARBIDE

Silicon carbide is made from petroleum coke and quartz sand or coal tar, wood chips, and other raw materials by smelting high-temperature electric resistance furnaces. In the high technology, non-oxide refractory raw materials, such as C, N, B, silicon carbide is the most widely used and one of the most economical material. It can be

Key Driving Factors of Black Silicon Carbide Market Black silicon carbide will quadruple its market value and continue holding more than half of the overall market share due to increasing usage in the automotive, steel, and construction industries. Electrical & electronics will triple their share in the end-user segment, on the back of silicon carbide’s

Black silicon carbide is brittle and sharp and has high hardness, low expansion coefficient，good thermal conductivity, and electrical conductivity. It takes petroleum coke and high-quality silicon as raw materials, adds salt as an additive and is fused through the electric resistance furnace at high temperatures. Hexagonal crystalline of microscopic shape, 3300kg/mm³ of microhardness. Its hardness
