  • Abstract
    High-purity (99.9+%) nanosize Cr2O3 was produced from chromite concentrates. Sodium dichromate was produced from an alkaline melt of chromite ore and then nanosize Cr2O3 was obtained by reaction between sodium dichromate and sulphur. Nanooxides were investigated by scanning electron microscopy, transmission electron microscopy and X-ray diffraction analysis. The size of particles was 50-148 nm. The nanoparticles show a loosely agglomerated structure. The presented method is simple and economical.
