摘要: The sinterability of magnesium oxide (MgO) doped hydroxyapatite (HA) ranging from 0.05 to 1 wt% was investigated. Green samples were prepared and sintered in air at temperatures 1000°C 1400°C. Sintered bodies characterized determine the phase stability, bulk density, hardness, fracture toughness Young’s modulus. XRD analysis revealed that HA stability not disrupted throughout sintering regime employed. In general, containing MgO when lower possessed better mechanical properties than undoped HA. study all achieved > 98% relative density between 1050°C−1300°C. addition 1150°C found be most beneficial studied range as exhibited highest modulus 136.3 GPa, Vickers’s hardness 7.66 GPa 1.48 MPam1/2 compared 113.57 7.10 1.08 for
