Acheson's technique for producing silicon carbide and graphite is named the Acheson process. In 1896, Acheson received a patent for his method of synthesizing graphite, and in 1897 started commercial production. The Acheson Graphite Co. was formed in 1899. Synthetic graphite can also be prepared from polyimide and commerciallized.
