The effects of microwave hybrid heating on the densification and decomposition behaviour of four commercially available pre-calcined HAp powders (Plasma Biotal P81, P88, P120 and P149) and a bead milled HAp powder (BM16) were studied. The results were compared with conventionally sintered samples. Samples microwave heated to 1100°C for 10 min at 10,000°C.h-1 were 15 to 40% denser than the samples conventionally heated at same temperature for 60 min at 300°C.h-1. Microwave heating reduced densification temperatures and soak times by as much as ~150°C-200°C and ~57 min, respectively. Overall, the microwave sintering cycle was 20-30 times faster.
