The invention relates to a method for producing hydroxyapatite coated ceramics components. In a first step of the inventive method the ceramic component is provided with a Ti coating and in a second step a hydroxyapatite is applied to the Ti coating. The invention further relates to hydroxyapatite coated ceramic components produced according to the inventive method.

Aluminum oxide ceramics with hydroxyapatite

The invention relates to a sintered shaped body comprising a matrix material that contains an aluminum oxide/chromium oxide mixed crystal and an additional mixed crystal selected from at least one mixed crystal according to one of the general formulas La Al Cr O , Me Al Cr O Me Al Cr O , Me Al Cr O and/or Me Al Cr O , wherein Me stands for an alkali metal, Me represents an alkaline earth metal, Me stands for cadmium, lead or mercury and Me represents a rare earth metal and x has a value ranging from 0.0007 to 0.045.

Sintered shaped body reinforced with platelets

Zirconium dioxide containing 2 to 40 vol. % of stabilizing oxides is embedded in the matrix material of a sintered molding consisting of an aluminum oxide/chromium oxide mixed crystal. The quantity of stabilizing oxides added is chosen so that the zirconium dioxide is predominantly tetragonal. The molar ratio of the zirconium dioxide containing the stabilizing oxides to the chromium oxide is between 1000:1 and 20:1 and the zirconium dioxide has a maximum particle size of 2 .mu.m.
