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.
