Boron Trioxide Properties

Boron Trioxide

Molecule Structure Image



Boron trioxide is one of the oxides of boron. It is one of the most difficult compounds known to crystallize. Boron trioxide is produced by treating borax with sulfuric acid in a fusion furnace. It is used in the production of boron, heat resistant glass, fire retardants for paints and cellulose insulation, boron carbide, and also in electronics.
