Abstract

We have studied chemical interaction between fluorine-substituted hydroxyapatite and metallic titanium in the temperature range 700–1000°C. The results indicate that the phase relations in this system differ markedly from those in the hydroxyapatite-titanium system under similar conditions. The most important result is that the apatite phase persists in the former system, whereas in the hydroxyapatite-titanium system the hydroxyapatite decomposes at 900°C to form calcium titanate. The process common to the two systems is the complete oxidation of titanium and the formation of rutile at temperatures above 800°C.
