Abstract: 
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.
