Applications

Boron oxide is used as a flux, an acid catalyst and a chemical intermediate in production of boron halides, esters, carbide, nitride and metallic borides. Boron oxide 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.

Notes

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