silicon carbide acheson furnace

Edward Goodrich Acheson

Edward Goodrich Acheson (1856–1931) was raised in the coal fields of southwestern Pennsylvania He left school at the age of 16 to help support his family after his father died but he devoted his evenings to scientific pursuits—primarily electrical experiments In 1880 he had the temerity to attempt to sell a battery of his own invention to Thomas Edison and wound up working

Silicon Carbide (SiC) Properties Production

Silicon carbide is composed of light elements silicon (Si) and carbon (C) Its basic building block is a crystal of four carbon atoms forming a tetrahedron covalently bonded to a single silicon atom at the centre SiC also exhibits polymorphism as it exists in different phases and crystalline structures [2][3]
