TECHNOLOGY OF OBTAINING BORIDE-CONTAINING CHROMIUM POWDERS BY THERMAL MAGNESIUM REDUCTION IN IONIC MELTS
Synthesis conditions of boride-containing chromium powders with the joint reduction of metal oxides and boron compounds in NaCl and NaF-NaCl melts at T = 1123…1173 K are considered. The content of boride phases in the composition of Cr-CrB composites is shown to reach 40…60 %. The specific surface of chromium powders is 23,38∙105 m-1.
