ABSTRACT:
A process for the production of a hydroxyapatite coated article includes contacting a coating comprising hydroxyapatite with a recrystallization medium, pressurizing the recrystallization medium, heating the coated article under conditions of reduced oxygen activity at a temperature in the range of 100 to 350.degree. C. A process for the production of highly crystalline hydroxyapatite coated articles includes contacting a coating comprising hydroxyapatite with recrystallization medium containing hydroxyapatite particles, pressurizing the recrystallization medium, and heating the immersed coated article under conditions effective to crystallize hydroxyapatite.
