Nanohydroxyapatites are at the forefront of biomaterials due to their biocompatible and bioactive properties, as well as promoting osseointegration due to their size. However, the weak mechanical properties of hydroxyapatites limit their use in areas that will be exposed to load transfer. In this study, the mechanical, structural and bioactivity properties of nanohydroxyapatite were investigated by doping nano zinc oxide. 90% nano hydroxyapatite with 10 wt % nano ZnO and 90 wt. % nano hydroxyapatite with 10 wt. % nano CIG by weight were subjected to mechanical alloying process separately for 4 hours. Afterwards, the mixtures were sintered at 760°C for 30 minutes by hot press method. Density value of hydroxyapatite composite with zinc oxide added after sintering is 2.94 g/cm3, Vickers hardness value is 380 HV, compression strength value is 127 MPa. The density of the commercial inert glass added hydroxyapatite composite was 2.76 g/cm3, the Vickers hardness value was 290 HV, and the compression strength value was 82 MPa.
