Product Description

Product Description

Chinese Supplier Factory Wholesale Price CAS 1303-86-2 Boron Oxide (B2O3)

Boron trioxide (chemical formula: B2O3), also known as boron oxide, is the most important oxide of boron. It is a white waxy solid that generally exists in an amorphous state and is difficult to form crystals, but can also crystallize after high strength annealing. It is one of the most difficult substances known to crystallize.
