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-carbide can be found in block-knife sharpeners, but I found they were too expensive. Instead, I used a silicone-carbide rubbing stone for under $14 found at the hardware store. The crucible I used was metal with a higher melting point that the melting I was attempting to smelt.
High temperature silicon carbide board and products are widely used in sintering of industrial ceramics, porcelain, artistic porcelain, high-grade sanitary ceramics, magnetic materials, electronic ceramics, etc.

SiC Production Process | Washington Mills
Silicon carbide crude is produced by mixing silica (SiO2) with carbon (C) in an electric resistance furnace at temperatures around 2,500 C. The chemical reaction in the SiC process may be represented by the formula: SiO2 + 3C SiC + 2CO Washington Mills
Nanorods of silicon carbide from silicon carbide …
Nanorods of silicon carbide were found to be produced directly from silicon carbide powder when subjected to high temperature heat treatment. The powder with 20–50 μm grain size was kept in a graphite crucible (enclosed in a chaer/furnace) and heated from its bottom at 2700 °C for 15 min by employing a typical configuration of arc plasma (Ar).
