Boron oxide

Boron oxide (Cat No.:M050043) is a white, glassy solid commonly used as a fluxing agent in glass and ceramic production. It is formed by the oxidation of elemental boron or the dehydration of boric acid. B₂O₃ lowers the melting point of silica, improving workability and thermal shock resistance in borosilicate glasses. It also enhances chemical durability and dielectric properties, making it valuable in optical materials, enamels, and specialty glasses. In organic synthesis, it serves as a catalyst or reagent. Boron oxide is hygroscopic and must be stored in moisture-free conditions to maintain its reactivity.
