The influence of nanoscale inhomogeneities on the phase-separation processes in calcium silicophosphate glasses of medical purpose is investigated. As revealed, the presence of drop-like nano- and microinhomogeneities in calcium silico-phosphate glasses renders a substantial influence on glass de-laminating in the precrystallization period and promotes fine crystallization of hydroxyapatite and rutile after heat treatment. It is established that a necessary condition for fine bulk crystallisation of calcium phosphates is keeping up of stoichiometric relation of phase-forming oxides in quanti-ties of 5 mol.% P2O5 and 8 mol.% CaO and presence of titanium oxide in quantity of 8 mol.% in glass composition.
