Silicon carbide is a chemical compound that is commonly used in the manufacturing of abrasives. This hard material is also useful in electronics and other applications where durability is a must. It is also used as abrasives for various purposes, including grinding, polishing, and cutting. The chemical compound can also be used in ceramics and light-emitting diodes. The material also plays a major role in crack-healing behavior.
Silicon carbide was first made around 1890 by Edward Goodrich Acheson, who patented the process in 1893. This process involved heating clay, aluminum silicate, and powdered coke in an iron bowl. The resulting material formed blue crystals that he called carborundum. Later, Moissan produced SiC through several methods.
Silicon carbide is a chemical compound composed of light elements such as silicon and carbon. The building block of silicon carbide is a tetrahedron composed of four carbon atoms covalently bonded to one silicon atom. The compound exists in different crystalline and phase structures and has different hardness values. The material's hardness makes it an excellent material for cutting tools and mechanical seals.
It is available as an irregularly shaped powder, crystals, platelets, and wafers. It can also be obtained in different size distributions, from coarse grits to nanometer particles.
