Ceramic matrix composite - Wikipedia

2019-4-5 · Silicon carbide. Pure silicon carbide is one of the most corrosion-resistant materials. Only strong bases, oxygen above about 800 °C, and molten metals react with it to form carbides and silicides. The reaction with oxygen forms SiO 2 and CO 2, whereby a surface layer of SiO 2 slows down subsequent oxidation (passive oxidation).

The Properties and Uses of Silicon Metal

Silicon metal is a grey and lustrous semi-conductive metal that is used to manufacture steel, solar cells, and microchips. Silicon is the second most abundant element in the earth''s crust (behind only oxygen) and the eighth most common element in the universe.

How silicon is made - material, making, history, used

When silicon is heated it reacts with the halogens (fluorine, chlorine, bromine, and iodine) to form halides. It reacts with certain metals to form silicides and when heated in an electric furnace with carbon, a wear resistant ceramic called silicon carbide is produced. Hydrofluoric acid is the only acid that affects silicon.
