structure of silicon carbide Pure silicon carbide is a colorless and transparent crystal. Industrial silicon carbide is light yellow, green, blue or even black due to the type and content of impurities, and its transparency varies with its purity. The crystal structure of silicon carbide is divided into hexagonal or rhombohedral α-SiC and cubic β-SiC

Green silicon carbide powder has higher hardness and mechanical strength than corundum Green silicon carbide powder is green, with crystal structure, high hardness, strong cutting ability, stable chemical properties and good thermal conductivity. The microscopic shape is hexagonal crystals. The Mohs hardness of silicon carbide is 9.2, and the Vickers micro hardness is 3000-3300 kg/mm.

Application of Silicon Carbide on Grinding Disc Grinding disc. Grinding discs are important process equipment for the production of silicon wafers for VLSI in the semiconductor industry. Grinding discs made of silicon carbide ceramics can be ground and polished at a high speed due to the high hardness of the grinding discs and the low

Analysis of the difference in purity and use of black silicon carbide and green silicon carbide Black silicon carbide contains about 98.5% of SiC, and its toughness is higher than that of green silicon carbide. It is mostly used to process materials with low tensile strength, such as glass, ceramics, stone, refractory materials, cast iron

Why do we need to add silicon carbide to the non-stick pan coating? Silicon carbide has extremely high hardness, good chemical properties and thermal conductivity. The shape is similar to a hexagonal crystal. It mainly uses petroleum coke and high-quality silicon as the main raw materials, and uses salt as an additive. It is refined
