Silicon carbide (SiC), also known as carborundum (/ ˌ k ɑːr b ə ˈ r ʌ n d əm /), is a hard chemical compound containing silicon and carbon. A wide bandgap semiconductor , it occurs in nature as the extremely rare mineral moissanite , but has been mass-produced as a powder and crystal since 1893 for use as an abrasive .
Edward Goodrich Acheson (March 9, 1856 – July 6, 1931) was an American chemist. [1] Born in Washington, Pennsylvania, he was the inventor of the Acheson process, which is still used to make silicon carbide (carborundum).
By 1896, The Carborundum Company was producing 1 million pounds of carborundum. [7] Many current silicon carbide plants use the same basic design as the first Acheson plant. In the first plant, sawdust and salt were added to the sand to control purity. The addition of salt was eliminated in the 1960s, due to it corroding steel structures.

Some of them, including titanium carbide and tungsten carbide, are important industrially and are used to coat metals in cutting tools. [3] The long-held view is that the carbon atoms fit into octahedral interstices in a close-packed metal lattice when the metal atom radius is greater than approximately 135 pm: [2]
