In order to obtain the Ca10(PO4)6(OH)2 / Fe3O4 composite systems, the synthesized materials Ca10(PO4)6(OH)2 / FeC2O4 are subjected to heat treatment in protective and restorative media for 2 h at T = 500 °С. It is established that both oxidation and reduction of magnetite are present in all materials. In this case, the hydrocarbon environment avoids significant phase transitions of magnetite. However, a more sophisticated crystalline structure (86%) is inherent in the Ca10(PO4)6(OH)2 / Fe3O4 materials obtained by the chemical method after vacuum heat treatment. In other words, the peculiarities of the phase composition of the powders depend predominantly on the medium in which thermolysis takes place. The method for adding magnetite has only a minor effect.
