Witryna6 lip 2007 · We performed first-principles calculations to investigate the possible magnetism induced by different concentrations of nonmagnetic impurities and vacancies in a $\mathrm{BN}$ sheet. Atoms of Be, B, C, N, O, Al, and Si are used to replace either B or N in the system as impurities. We discuss the changes in the … WitrynaThe B and BN impurities to be removed react with oxygen or water in the form of steam to form boron oxide, B 2 O 3. Continuous exposure of boron oxide to steam results in the formation of meta-boric acid ([BOH] 3 O 3) which is converted to aqueous boric acid (B(OH) 3) and carried away as effluent exposing more surface for the reaction. In ...
