Boron Oxide specification:
1 Molecule formula : B2O3
2 Molecule weight : 69.62
3 Melting point : 450°C
4 Boiling point : 1860°C
5 Density : 1.085 gram per ml (Amorphous)
6 Solubility : The product can be dissolved in acid, ethanol, hot
water, and slightly dissolved in cold water.
7 Property:It is a colorless transparent crystal powder. Its
surface has greasy feeling its hygroscopicity is strong and it is
easy to be hydrolyzed to form boric acid. In high temperature, it
can be reduced by alkali metal or magnesium to monocrystal boron,
It can be completely mixed dissolved with the oxides of metal,
copper, sliver, aluminum, tin, arsenic.
Boron Oxide usage:
It is used as the flux in decomposition of silicates the mixing
agent of semiconductor material,the additives of heatproof
glassware and paint refractory. It is also used in production of
alloy steel in metallurgical industry. In addition it’s used as the
catalyst in organic synthesis, the additive of lubricant used in
high temperature, can be also used an environmental protection.
