Abstract

Bioactive titania gel was derived from chemical treatment of Ti substrate with dilute H2O2 solutions and subsequent thermal treatments. We examined the effects of the chemical treatment time and the concentration and pH of the H2O2 solutions on both formation of titania gel and in vitro deposition of apatite or bioactivity. The optimum treatments consisted of 6 mass% H2O2 treatment at 60 °C for 3-6 h and subsequent thermal treatment at 400 °C for 1 h. Reactions between the titanium substrates and H2O2 involved the oxidation of titanium, titania gel formation and Ti dissolution.
