애플리케이션

Boric anhydride in sulfuric acid may be used as a scrubber to remove the hydrogen fluoride gas formed as a byproduct during the selective reduction of ketones to hydrocarbons using triethylsilane and boron trifluoride. In combination with hydroxyapatite, it may be used to catalyze the vapor-phase Beckmann rearrangement process to form nylon-6.

Mg2B2O5 nanowires with (010) twins were synthesized for the first time using a catalyst-free method. The microstructure of the Mg2B2O5 nanowires has been extensively studied by cross-sectional high-resolution transmission electron microscopy. Nanoindentation tests were performed directly on individual nanowires to
