چکیده انگلیسی
This paper presents the effect of Zirconia (ZrO2 =â¯0, 5, 10, 15, 20 and 25â¯wt%) on the mechanical properties and micro structural studies of Hydroxyapatite (Ca10(PO4)6(OH)2) (HAp) nano composites. HAp and Zirconia nano composites of 20-40â¯nm were produced using High Energy Ball milling at 300â¯rpm for 1â¯h. X-ray diffraction studies showed that the crystallite and grain size gradually decreased with the increase in ZrO2 content till 20â¯wt%, after which there was a sudden raise in both parameters. A dominant ZrO2 phase was observed in X-ray diffraction studies of sintered samples. Mechanical properties were found to significantly improve on adding 20â¯wt% of ZrO2 at 1200â¯Â°C. However, the addition of 25â¯wt% of ZrO2 powder decreased the mechanical properties of HAp. The reduction could be due to the increase in grain size and dominant smaller particles of ZrO2. The improved mechanical properties were correlated with the observed micro structural features.
