DESCRIPTION
Silicon carbide (SiC) is a high-performance ceramic material with excellent mechanical, electrical, and thermal properties. It is a compound of silicon and carbon, and is commonly known as carborundum. Silicon carbide can be found in different forms, including powder, sintered shapes, and bonded abrasive products. Silicon carbide powder is widely used in the manufacturing of abrasives, cutting tools, refractory materials, and ceramics. It is also used in the production of semiconductors, as it has unique electronic properties such as high thermal conductivity, high breakdown voltage, and low thermal expansion coefficient. The powder can also be used as a raw material for the production of silicon carbide fibers and other advanced composite materials. Sintered silicon carbide products offer high strength, hardness, and wear resistance, and are used in applications such as mechanical seals, bearings, and pump parts. Bonded abrasive products, such as grinding wheels and cutting discs, are made by combining silicon carbide abrasive grains with a binder material.
