Hydroxyapatite (HA) is an effective material used in bone prostheses. The activating and sintering characteristics of hydroxyapatite agglomerate treated by shock wave were studied. Using XRD and SEM the grain size refinement, homogenization and lattice deformation were observed in shocked HA powders, which can promote sintering of HA ceramics. The extra energy stored in shocked powders will be released during sintering process. The temperature of maximum shrink rate of shocked sample is about 70 lower than that of unshocked one. The strength and density of HA ceramics from the shocked sample can be enhanced. HA ceramics with high strength used for artificial bone materials can be made with the shock-activating method.
