应用
Boric anhydride also referred to as boron trioxide or boron oxide (B2O3) has been used for preparing specimens of Bi4B2O9 ceramics. It has also been used for WO3/B2O3/Al system for investigating the impact of Ar gas pressure on the SHS reaction products.
生化/生理作用
Boric anhydride is an oxide of boron that shows antimicrobial property along with lower aminoalcohols.

Boron-11 and silicon-29 NMR spectra of xSiO(2)-(1-x)B(2)O(3) glasses (x=0.40, 0.80 and 0.83) have been calculated using a combination of molecular dynamics (MD) simulations with density functional theory (DFT) calculations of NMR parameters. Structure models of 200 atoms have been generated

CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics directly bond to bone and have potential use as a bone substitute material. The present study evaluated the toxicity from subchronic intravenous administration of CaO-SiO(2)-P(2)O(5)-B(2)O(3) glass ceramics to male and female Sprague-Dawley rats. The rats were divided
