The present work relates to a process for the production of nano particles pigment and relates particularly to the production of nano composite powders consisting of individual particles with sizes in the range of 10 nm to 100 nm. This process involves the mechanically activated chemical reduction of reducible metal compounds during milling, to refine and manufacture nano com- posite powder. Nano particle pigment for ceramic glazes was obtained by mechanochemical inser-tion of Fe-Cr-Ti in an α-Al2O3 host matrix. Iron, chromium and titanium oxides were reduced by milling with metallic aluminium with subsequent formation of additional Al2O3 by oxidation of aluminium. XRD (X-ray diffraction) and BET (Brunauer, Emmett and Teller) have been used for investigation of phases and particle size of powder
