Abstract

CaO-P2O5 glass ceramics with small additions of MgO and TiO2 were prepared in the ortho and pyrophosphate regions by powder sintering and crystallisation through heat treatment at different temperatures determined from differential thermal analysis (DTA). The glass ceramics were analysed by x-ray diffraction (XRD) and it was observed that α- and β-Ca2P2O7 were the first phases to precipitate in the parent glass matrix at a temperature of 681°C, followed by CaTi4(PO4)6 and TiP 2O7 at temperatures between 703 and 725°C. The β-Ca2P2O7 and CaTi4(PO 4)6 phases are usually considered as biocompatible and bioactive and, therefore, these glass ceramics seem to show good potential for bone regeneration applications.
