✦ Synopsis

Conditions of glass formation in the (\mathrm{Na}{2} \mathrm{O}-\mathrm{TiO}{2}-\mathrm{P}{2} \mathrm{O}{5}) system are reported. The largest quantity of (\mathrm{TiO}{2}) which can be introduced is (35 \mathrm{~mole} %). Study of the recrystallization process leads to the identification of a new Nasicon-type phosphate, (\mathrm{Na}{5} \mathrm{Ti}\left(\mathrm{PO}{4}\right){3}). In glasses the (\mathrm{Ti}^{44}) ions are presumably located in both pyramidal and octahedral oxygenated sites. O 1993 Academic Press. Inc.

## Abstract Bioactive glasses react chemically with body fluids in a manner that is compatible with the repair processes of the tissues. This results in the formation of an interfacial bond between the glasses and living tissue. Bioactive glasses also stimulate bone–cell proliferation. This behavio
