Properties of magnesium doped nanocrystalline hydroxyapatite synthesize by mechanochemical method

The sintering behaviour of Magnesium-doped nanocrystalline hydroxyapatite (MgHA) synthesized by mechanochemical method was investigated over the temperature range of 1000 °C to 1300 °C. The properties were investigated in terms of phase stability, bulk density and Vickers hardness. In the present re...
