Kinetics of diamond-silicon reaction under high pressure …
In this dissertation work, the kinetics of the reaction between diamond and silicon at high pressure-high temperature conditions was investigated. This study was motivated by the extremely limited amount of information related to the kinetics of the reaction in diamond-silicon carbide composites formation. It was found that the reaction between diamond and melted silicon and the subsequent

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).
