acheson process graphite

Acheson process - Oxford Reference

09/04/2021  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).

The common manufacturing process used to synthesize graphite, known as Acheson process, 23 relies on thermal heating of amorphous carbon to 3000 °C. Although the energy requirements are enormous, (typical processing time is 2 weeks) the Acheson process remains the major industrial process since its invention in the 1960s. 3 Several researches about different way of graphitization

Acheson process technology Britannica

Other articles where Acheson process is discussed: refractory: Silicon carbide: In the Acheson process, pure silica sand and finely divided carbon (coke) are reacted in an electric furnace at temperatures in the range of 2,200°–2,480° C (4,000°–4,500° F). SiC ceramics have outstanding high-temperature load-bearing strength and dimensional stability.

Graphite - Industrial Minerals

Graphite is one of most versatile of non-metallic minerals. It is one of four main natural forms of carbon along with coke, coal, anthracite and diamond. Graphite can also be manufactured synthetically, primarily via the Acheson Process which utilises lower purity carbon-bearing raw materials blended with tar pitch. Natural graphite is produced in three commercial forms: amorphous (60-85%C ...
