Abstract
The structural and morphological properties of powders of commercial amorphous boron grade B modified with acetonitrile, weak nitric acid, and fluorine-containing compounds are studied by the Brunauer, Emmett and Teller (BET), scanning electron microscopy (SEM), and Raman spectroscopy methods. The influence of these properties on the oxidation of powders is analyzed using thermogravimetric analysis (TGA). It is shown that the removal of the surface layer in the form of boron oxide and boric acid leads to a more complete oxidation degree of the powder.
