  • Acheson process Oxford Reference

    An industrial process for the manufacture of graphite by heating coke mixed with clay The reaction involves the production of silicon carbide, which loses silicon at 4150°C to leave graphite The process was patented in 1896 by the US inventor Edward Goodrich Acheson (1856–1931)29/03/2021· The Acheson furnace is divided into two stages in its development process, namely the initial AC graphitization furnace and the DC graphitization furnace developed after the 1960s Although the two adopt the same furnace shape, the direct current furnace is superior to the AC furnace in various technical indicators due to the different types of currents Therefore, the direct current furnaceWhat is acheson graphitization furnace? Advantages of20/10/2018· Acheson process is an industrial process to synthesize graphite and silicon carbide (carborundum), named after its inventor the American chemist Edward Goodrich Acheson (18561931) In this process, a solidstate reaction between pure silica sand (SiO 2 ) and petroleum coke (C) at very high temperature (more than 2500 °C) leads to the formation of silicon carbide under the generalAcheson process @ Chemistry Dictionary & Glossary
