Abstract

The changes in the phase composition of basalt scale-reinforced hydroxуapatite composite systems with different component ratio, depending on the annealing temperature of the powder mixture and after the interaction of the latter with biological environments simulating life environments, are investigated. It is established that after the interaction of HAP + BS composite system annealed at 1200 °C with corresponding biological environments the X-ray diffraction pattern discovers additional phases. Furthermore, the oxidation of Fe3O4 into Fe2O3 is observed. It is established that the HAP + 10% BS composite system annealed at 900 °C is the most promising material for the intraosteal reconstruction surgery (anaplastic surgery) from the point of view of physicochemical stability in biological environments and the strength properties similar to those of the natural bone.
