Abstract
Vanadium boride (VB) nanopowder was synthesized by mechanochemical combustion method in a high-energy ball mill. The synthesized powders were analyzed by X-ray diffraction (XRD), differential thermal analysis (DTA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicated that the reaction between Mg, V2O5 and B2O3 mixture was highly exothermic and operated in a combustion mode. XRD analysis showed that the vanadium boride was formed after 100min milling time without any further heat treatment. The TEM results showed that the obtained vanadium boride aggregates were composed of nano-sized primary particles with a mean diameter of about 36nm.
