In this work calcium phosphate (CaP) compounds with different PO 4 3Οͺ / HPO 4 2Οͺ R molar ratios in the 0.65-149 range were synthesized. In fact, all these CaPs contain different amounts of HPO 4 2Οͺ and PO 4 3Οͺ ions as well as the amorphous precursors (tricalcium phosphate and octacalcium phosphate)
Hydroxylapatite (HA) and tricalcium phosphate (TCP) composites with lanthanum phosphate were prepared with pressureless air sintering at 500, 700, 900, 1100 and 1300 β’ C for 2 h. The composites were characterized in terms of phase stability during sintering, microstructural evaluation with XRD, SEM
