ABSTRACT:
The present invention discloses a method for making a molded calcium phosphate article including impregnating a rigid shaped article of calcium phosphate in an impregnating liquid for a period of time so that a compressive strength of the resulting impregnated article removed from the impregnating liquid is increased compared to that of the rigid shaped article. The molded calcium phosphate article made according to the present invention may be used as a medical implant or a reinforcing constituent of a composite.
