Microhardness of Hydroxyapatite Doped ZrO2 using Sol-Gel Method

Calcium Phosphate based bio-ceramics in the form of hydroxyapatite (HA) with high biocompatibility in hard tissues. In this work HA mixed with ZrO2 using Sol-gel method. Calcium nitrate with Di-ammonium hydrogen phosphate used for the formation of HA, which exhibited less mechanical property. To overcome these problems ZrO2 were used to increase its mechanical strength.XRD and FTIR confirmed the phases and functional groups and its hardness was analysed and confirmed it is a soft material used in various medical applications especially in orthopaedics field.
