Exploring the use of silica sands and calcite from natural deposits to prepare bioactive glasses.

Nowadays bioactive glasses represent one of the most successful bioceramics used for bone tissue restorations. In this work, three types of silica sands (White, Yellow and Gray Sands) and calcite from Cuban natural deposits were employed to synthesize glasses from the system SiO2-CaO-Na2O. The ions...
