footnotes =Edward Goodrich Acheson [ [http://www.chemheritage.org/classroom/chemach/electrochem/acheson.html Edward Goodrich Acheson] ] (
March 9 ,1856 -July 6 ,1931 ) was an Americanchemist . Born inWashington, Pennsylvania , he was the inventor ofcarborundum [ [http://inventors.about.com/library/inventors/blacheson.htm Edward Goodrich Acheson - Carborundum ] ] , and later a manufacturer of carborundum andgraphite .Thomas Edison put him to work onSeptember 12 ,1880 at hisMenlo Park , New Jersey laboratory underJohn Kruesi . Acheson experimented on making a conducting carbon that Edison could use in his electric light bulbs.In 1884, Acheson left Edison and became supervisor at a plant competing to manufacture electric lamps. He began working on the development of Cubic Zirconium (artificial diamonds) It was here he began his own experiments on methods for producing artificial diamonds in an electric furnace. He heated a mixture of clay and coke in an iron bowl with a carbon arc light and found some shiny, hexagonal crystals (silicon carbide) attached to the carbon electrode.
In 1891 Acheson built an electricity plant in
Port Huron at the suggestion of Edison, and used the electricity to experiment with carborundum. OnFebruary 28 ,1893 , he received a patent on this highly effective abrasive although a 1900 decision gave "priority broadly" to theElectric Smelting and Aluminum Company "for reducing ores and other substances by the incandescent method". [cite journal|author=Mabery, Charles F.|title=Notes, On Carborundum|pages=706–707|url=http://books.google.com/books?id=fBIDAAAAYAAJ&pg=PA706|date=1900|volume=XXII|issue=Part II|journal=Journal of the American Chemical Society|publisher=Johnson Reprint Company, via Google Books scan of Harvard University copy|accessdate=2007-10-28]Carborundum is silicon carbide and it is created by electronically fusing clay and carbon. It is the second hardest surface next to diamond. Throughout Acheson's life, he received 70 patents relating to abrasives, graphite products, reduction of oxides, and refractories.
He died on
July 6 ,1931 , inNew York City .In 1997, he was inducted into the
National Inventors Hall of Fame .Notes
