Boron trioxide, with the chemical formula B2O3, is a white, glassy solid that is commonly used in the production of glass and ceramics. It serves as a flux, lowering the melting point of silica and improving the workability of glass materials. Additionally, it is utilized in the manufacture of fiberglass and as a component in some types of adhesives. In nature, boron trioxide can be found in various minerals and is often produced by the oxidation of boron compounds. It has applications in the chemical industry, including the production of boron-containing compounds and as a catalyst in certain reactions.
