The study is devoted to synthesis and preliminary structural and morphological characterization of modified 45S5 glasses, in (66-x)SiO2∙27CaO∙4P2O5∙3TiO2∙xAl2O3 system, with potential applications in dentistry. The composition of the sol-gel derived samples was verified with respect to their nominal composition. The effect of partial SiO2 replacement with Al2O3 on samples structure and morphology is investigated. It was established that the Ca/P ratio is diminished in Al2O3 containing samples and that an amorphous hydroxyapatite phase similar to hydroxyapatite reported for bone tissue is formed.
