In the present investigation the effects of milling parameters (time, atmosphere, and media) andchemical composition of raw materials on the mechanochemical synthesis of nanocrystallinehydroxyapatite (n-HAp) were studied. For a comparative study of the mechanically activated samplesversus thermally treated specimen (natural origin), n-HAp was also produced via annealing of bovinebone at 800℃ for 2 h. The gained powders exhibited average sizes about 32 and 27 nm under airatmosphere, and about 32 and 34 nm under argon atmosphere. TEM images confirmed the formation ofn-HAp with various morphologies under different experimental conditions.
