Weak acid leaching of MgB$_2$ to purify magnesiothermic boron powder
We have established a new procedure for recovering boron contained in oxidized MgB$_2$ phase. Incorrect conditions of synthesis or conservation, or excess impurities in precursors, can lead to MgO formation with consequent degradation of superconducting properties, thus representing a possible probl...
