Abstract: Hot pressing of hydroxyapatite(HA)-Ti system material and the stability of HA component were investigated to supply the foundation of optimizing sintering procedure of HA-Ti functionally graded material(FGM). The result show that the HA powders used have excellent thermal stability and no decomposition is observed at 1 300℃. The existence of Ti can promote the dehydration and decomposition of HA. However, no new compounds form between HA an Ti. By selecting sintering parameters properly, ideal HA-Ti material can be acquired. The relative densities of the mixtures of HA and Ti are always lower than those of pure HA or Ti, which may be caused by the decomposition of HA in thmixtures.
