    Purification of amorphous boron powder by using the soluble transformation of acid-insoluble boron magnesium compounds by Lv S.-X., Cao Z., Wu J.-J.

    Published 2024-01-01
    “…Amorphous boron powder produced by magnesium thermal reduction contains many impurities that are insoluble in acids as well as defects such as low purity, excessive particle size, and poor chemical activity, which seriously hinder its large-scale application in the military and aerospace fields. In this paper, the soluble transformation mechanism of insoluble boron magnesium compounds into amorphous boron powder during calcination and a method for purification boron powder were studied. …”
