Silicon carbide - Wikipedia

Because natural moissanite is extremely scarce, most silicon carbide is synthetic. Silicon carbide is used as an abrasive, as well as a semiconductor and diamond simulant of gem quality. The simplest process to manufacture silicon carbide is to coine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1,600 C (2,910 F) and 2,500 C (4,530 F).

Silicon Oxycarbide Glasses | SpringerLink

The first attempts to introduce carbon into glass date back to 1951. But up until recently, the use of carbon or carbide raw materials, and the oxidation, volatilization and decomposition that accompany high temperature melting, have limited the synthesis of true silicon oxycarbide glasses. Here, the term silicon-oxycarbide refers specifically to a carbon-containing silie glass wherein
