General note In this study , Alumina (Al2O3) and hydroxyapatite (HAP) composite were prepared by using<br/>powder metallurgy (PM) technique of vacuum sintering. As alumina non osteoinductive its<br/>bio- inertness did not allow bone ingrowth. To obtain a novel material for load bearing<br/>biomedical applications with relatively low lower modulus, adequate strength as well as<br/>excellent biocompatibility Alumina (Al2O3) and hydroxyapatite (HAP) composite that<br/>possess bio inertness and biocompatibility have been developed. For proper characterization<br/>purpose four compositions of the composite were prepared with Alumina concentration of<br/>60,70,80 and 90 percent and Hydroxyapatite concentration of 40,30,20 and 10 percent of the<br/>two total volume. Powders were mixed by using Ball Mill and Cold compacted by using<br/>hydraulic press. The green pellets were vacuum sintered at 1300°C and 1350 °C for 2,3 and<br/>4 hours of dwell time . Then all samples grinded and polished for characterization.<br/>Micostructure of the samples was analyzed by scanning electron microscope and optical<br/>microscope to onserve the uniformity of powders distribution and densification. Moreover<br/>density and micro hardness test were carried out to assess the mechanical strength of the<br/>sintered samples.<br/>According to research results, mechanical properties of the composites are increased by<br/>increasing the concentration of Al2O3 and decreased by increasing the amount of HAP. And<br/>the composition with 70% alumina and 30% of hap was considered as best for biomedical<br/>applications when it is sintered at 1350°C for four hours.
