Hydroxylapatite composites with lanthanum phosphate 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 higher than 700 degrees C, hydroxylapatite and lanthanum phosphate phase reacted and formed Ca-8 La-2 (PO4)(6)O-2 as byproduct. In the mean time, hydroxylapatite decomposed and formed tricalcium phosphate.
