Abstract
A process for manufacturing an apatite ceramic, especially for biological use involves the preparation of a homogeneous mixture of powders to form a hydroxyapatite of formula Ca10(PO4)6(OH)2, stoichiometric or non-stoichiometric, possibly containing other additives or flaws, compacting the mixture under a pressure of 100 to 500 Mpa at room temperature, and subjecting it to hydrothermal treatment at low temperature (100 to 500° C.) in the presence of water and in a sealed chamber.
