ABSTRACT:
In dental surgery and orthopedic surgery, implants of the bio-compatible hydroxyphosphate are used. Molded bodies or a granulate thereof are obtained by sintering in a moist oxygen atmosphere. These products are of a blue color. In accordance with the invention, white products are obtained by sintering in an inert atmosphere in which the oxygen concentration is maximally 0.005%.
