Alumina | chemical compound | Britannica

The toughness of alumina can be improved by the addition of zirconia particles or silicon-carbide whiskers, making it suitable for industrial cutting tools. Also, the normally opaque material can be made translucent by adding small amounts of magnesia. Translucent alumina is employed as the gas container in high-pressure sodium-vapour streetlamps.

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.
