The Properties and Uses of Silicon Metal

15/8/2019· To produce artificial diamonds in 1890, Edward Goodrich Acheson heated aluminum silie with powdered coke and incidentally produced silicon carbide (SiC). Three years later Acheson had patented his production method and founded Carborundum Company (carborundum being the common name for silicon carbide at the time) for the purpose of making and selling abrasive products.
