Under different sintering temperatures we synthesized examples of composition materials like gydroxyapatite-glass, in which we added Fe and Fe304 powders in quantity of 1 and 2% (mas.). We determined that sintering of composites with ferromagnetic additives in regular atmospheric conditions under temperatures higher than 500 °С leads to significant reduce of magnetite suspectibility comparing to sintering of samples in vacuum under the same temperatures. We studied how ferromagnetic additives in composite samples influence on its dissolution rate in vitro.
