We examined the effects of the thermal treatment temperature and Ta(V) species on in vitro apatite forming-ability of titania due to chemical treatment of titanium substrates. The formation of peroxo Ta(V) species (Ta(V)O2) in the H2O2 solution at 60°C effectively promoted not only the decomposition and the elimination of the peroxo and hydroperoxide groups, such as Ti-OOH and Ta-OOH in the titania gel but also the decomposition of H2O2 compared with the formation of peroxo Ti(IV) species (Ti(IV)O2), resulting in enhanced ability of apatite deposition in spite of thermal treatment at the lower temperature such as 100°C. The combined chemical and thermal treatments were applicable for providing both pieces of Ti and Ti mesh with bioactivity.
