Abstract
A silicate-based glass composition includes 15-65 wt. % SiO2, 15-50 wt. % CaO, 1-30 wt. % P2O5, and 1-20 wt. % ZrO2, such that the composition has a hydrolytic resistance of glass grains (HGB) of at most 3, when measured by International Organization for Standardization section 719 (ISO 719), and forms a bioactive crystalline phase in simulated body fluid.
