Abstract: 

A relatively easy method to synthesize pure and stable crystalline hydroxyapatite (HA) at low temperature by sol-gel route is presented. In this study phase purity of HA synthesized by sol-gel route was explored using calcium nitrate tetrahydrate and triethyl phosphate as calcium and phosphorus precursors, respectively. For some of samples, phosphorus sol was first hydrolyzed for 24 h with distilled water. Effects of sol-gel process parameters including mixed sol solution temperature, aging time and heat treatment on apatite phase evolution were systematically studied. Infrared (IR) spectroscopy, X-ray diffraction (XRD), thermal behavior (DTA) and elemental analysis of electron microscopy examination (SEM) were used for structural evolution investigation during the synthesis of HA. Increasing the aging time favors the reduction of CaO formation. Also, increasing the mixed sol solution temperature up to 80 had a positive effect on the elimination of impurity phases. With the increase of the calcination temperature > 600 °C, calcium phosphate impurity phases disappeared. The SEM micrographs showed highly agglomerated micro structure at nanoscale for calcined powders.
