Abstract

The results demonstrate the influence of the mass ratio of CaO/P2O5 and the total content of oxides (Na2O + CaO) in low-silica glasses of the Na2O–CaO–ZnO–SiO2–P2O5 system on their tendency to crystallization, bioactivity, and the size of the temperature range Tx–Tg, which determines the manufacturability of the glass being studied. The influence of the duration of interaction between the SBF solution and monolithic glass samples is established for the main characteristics used to describe the behavior of glasses in vitro: the pH of the SBF solution, the concentration of calcium ions in this model environment, and the formation of calcium phosphate phases with an apatite-like structure on the surface of the glasses.
