Description

Application

Boric anhydride also referred to as boron trioxide or boron oxide (B₂O₃) has been used for preparing specimens of Bi₄B₂O₉ceramics. It has also been used for WO₃/B₂O₃/Al system for investigating the impact of Ar gas pressure on the SHS reaction products.

Biochem/physiol Actions

Boric anhydride is an oxide of boron that shows antimicrobial property along with lower aminoalcohols.
