Silicon carbide manufacturing process

1. Powder preparation. Silicon carbide (SiC) is a compound of silicon and carbon with a chemical formula of SiC. The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F).

Silicon Carbide

Pure silicon carbide can be made by the so-called Lely process, in which SiC powder is sublimated in argon atmosphere at 2500 °C and redeposited into flake-like single crystals, sized up to 2×2 cm2, at a slightly colder substrate. This process yields high-quality single crystals, mostly of 6H-SiC phase (because of high growth temperature).

When it is energized, the heating starts. The core body temperature is about 2500°C or even higher (2600 ~ 2700°C). When the charge reaches 1450°C, the synthesis of SiC is started (but SiC is mainly formed at ≥ 1800°C), and CO is released. However, SiC will decompose at ≥ 2600°C, but the decomposed Si will form SiC with C in the charge.
