N2 - Tricalcium phosphate (TCP) composites with lanthanum phosphate were prepared with pressureless air sintering at 500. 700, 900, 1100 and 1300°C for 2 hrs. The composites were characterized in terms of phase stability during sintering, inicrostructural evaluation with XRD. SEM and machinability with simple drilling operation. Tricalcium phosphate and lanthanum phosphate phases were stable up to I 1 00°C. However, partial reaction forming Ca8La2(P04)602 was observed during sintering at 1300°C. As a result, tricalciuin phosphate and lanthanum phosphate composites sintered at I 100°C showed phase stability insuring weak interface. Thus, these composites fulfilled the requirement for machinability.
