Chemical Information

Boron oxide (B2O3)

Boron oxide appears as colorless, semi-transparent glassy lumps or hard white odorless crystals. Mp 450 °C; bp: 1860 °C. Density: 2.46 g cm-3. Moderately soluble in water. Used as an insecticide; as the starting material for the synthesis of other boron compounds; as a fluxing agent in enamels and glasses; and in mixture with 2-6% boron nitride, as a bonding agent in the hot isostatic pressing of boron nitride ceramics.
