Silicon carbide manufacturing process GAB Neumann
The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F) Fine silicon particles can be converted to silicon carbide (SiC) by heating in the excess carbon from the organic materialIf a cyclone is fed with a sand and water mixture containing a range of particle sizes, setting up a “whirlpool” flow pattern, with an air core (or vortex) a finer cutpoint on chrome minerals (SG 4) than it will on silica sand (SG 26) or coal (SG 15) Denser feed liquid (eg brine) will give a coarser cutpointIntroduction to Cyclones AusIMM
