The biological properties of a titanium (Ti) implant depend on its surface oxide film. The aims of the present study were to increase the specific surface oxide area on Ti using a porous structure, and study the relationship between the amounts of apatite coating in simulated body fluid (SBF) and the actual surface area on titanium powders. The amounts of precipitates through the compacts, which had been sintered of the powders with 110 micon meter diameter, were compared with those of the Ti plate. It was confirmed that the amounts of precipitates through the compacts were more than one hundred times higher than those on the Ti plates. It was concluded that the Ti porous compacts extract the surface property effectively.
