Hydroxylapatite composites with calcium titanium oxide were prepared with pressureless air sintering for 2 hours at different temperatures between 500 degrees C and 1300 degrees C. The interaction between the phases was monitored with XRD analysis. At sintering temperatures near 1100 degrees C, Slight decomposition of hydroxylapatite and formation of tricalcium phosphate was observed. However, sintering at the temperature higher than 1100 degrees C, tricalcium phosphate disappeared most probably due to the incorporation of CaTiO3 in the hydroxylapatite structure.
