摘要
Nanosized antimony was prepared by mechanochemical reduction of antimony sulphide (Sb2S) with elemental Mg. High-energy milling was performed in a planetary ball mill for 10-120 min. The composition and properties of the obtained powders were analyzed by XRD, specific surface area measurements and SEM. Most of the reaction took place as a self-sustaining reaction between 20 and 30 min, with only microstructural changes occurring during additional milling. Mechanochemical reduction is a very straightforward, one-step, ambient temperature process that can be readily utilized to make Sb nanoparticles.
