Anwendungen

In the electronics industry as a liquid encapsulent for Czochralski-type growth of III-V semiconductor single crystals (e.g., GaAs, GaP, InP).Boron oxide is used as a flux, an acid catalyst and a chemical intermediate in the production of boron halides, esters, carbide, nitride and metallic borides. It has shown a promising effect on glycerol hydrogenolysis to 1,2-propanediol. It is also an essential material for the preparation of cordierite ceramics from talc. It is actively involved in the production of borosilicate glass. It is an additive used in high-temperature lubricants, heatproof glasswares and dopants in semiconductor materials.

Bemerkungen

Hygroscopic and moisture sensitive. Incompatible with acids and strong oxidizing agents.
