Sintered porous titanium compacts, which have continuous pores, were fabricated by spark plasma sintering (SPS) process. Three different spherical particle sizes of Ti powders (45,150 and 250μm under) were employed to sinter the specimens. To evaluate the degree of sintering by SPS process, the sintered specimens were annealed at 1000℃ for 24 hours in an evacuated furnace. Compressive stress-strain curve of the annealed specimens were measured, and compared with those of the specimens by only SPS process. The sintered compacts were immersed in simulated body fluid (SBF) and evaluate the biocompatibility. Calcium phosphate (HAp) were precipitated on the sintered particles. Because precipitated HAp, is a main component of bone structure, the compact developed might be an advanced biomaterial with excellent biocompatibility and could control its mechanical properties by the heat treatment after SPS process.
