Flotation of Silicon Carbide

26/2/2018· Silicon carbide (SiC) is a synthetic compound which is commercially produced by heating a mixture of metallurgical coke and high-purity silica sand to 2,400° C in an electrical resistance furnace. A method to produce SiC was first discovered in this country by E. G. Acheson in 1891 while studying the reaction of carbon with other materials.

silicon carbide coating process | KSB

Using an old hotplate, Pickel experimented with tin, wax and quartz sand until he had found how silicon carbide could be applied to the inside of pumps during the casting process. He was then certain that his idea could help KSB to optimise its pumps. As his makeshift equipment at home had reached its limits, Pickel presented his idea to KSB.
