Investigation of Phase Separation Processes for Bioactive Glasses in Na2О–CаO–ZnO–TiO2–ZrO2–Al2O3–B2O3–P2O5–SiO2 Sysytem
Nanostructural changes on initial stages of calcium silicophosphate glasses nucleation in Na2О–CаO–ZnO–TiO2–ZrO2–Al2O3–B2O3–P2O5–SiO2 system during phase separation have been investigated. It has been established that the presence of drop-shaped nano- and micro-nonuniformities in the structure of calcium silicophosphate glasses substantially affects the glass separation in a precrystallization period, helping intense fine hydroxyapatite crystallization with the crystal size of up to 1 μm after heat treatment.
