Product Description

Product Description

Boron trioxide
English another name: Boric oxide, Boron oxide, Boric anhydride
CAS : 1303-86-2
1. Physical and chemical properties:
 Molecular formula: B2O3
 Molecular weight: 69.6
 Melting point: 450ºC
 Boiling point:1860ºC
 Density: 1.085 g/mL (Amorphous)
 Solubility: Dissolved in acid, ethanol, hot water, and slightly dissolved in cold water.
Properties: Colorless crystal powder. Be greasy in the surface. With strong hygroscopicity, it is easy to be hydrolysised to form boric acid. In high temperature, it can be reduced by alkali metal or magnesium to monocrystal boron. It can be completely mixed with the oxides of metal, copper, sliver, aluminum, tin.
