Silicon carbide — Wikipedia Republished // WIKI 2
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).

To create an even larger mirror, we investigated the use of reaction-formed joint technology. 7 In large-scale mirrors, the joints between mirrors must have good mechanical strength and environmental stability that are comparable with the bulk materials (the monolithic silicon carbide green body).

Silicon carbide as the third generation of space mirror material has attracted more and more attention and is widely applied. Silicon carbides prepared by different preparation methods have their advantages, but still cannot meet the optical requirements (<1 nm RMS) after the current optical processing.
