Abstract: The article presents the results of synthesis and studies of the physico-chemical properties of biomaterials based on oxide system SiO[2]-P[2]O[5]-CaO-MgO. Solution with different contents of calcium and magnesium were prepared by the sol-gel method. Tetraethyl orthosilicate (TEOS), phosphoric acid (H[3]PO[4]), calcium nitrate (Ca(NO[3])[2]·4H[2]O) and magnesium nitrate (Mg(NO[3])[2]·6H[2]O) in ethanol (C[2]H[5]OH) were used for preparation of solution. Viscosity of the solutions was 1,72-1,82 mm{2}/s on the first day. Powder X-ray diffraction showed at 800°С in the samples fixed phases quartz SiO[2], whitlockite (Ca[2],589 Mg0,411 )(PO[4])2, [beta]-cristobalite high SiO[2], stanfieldite Mg[3]Ca[3](PO[4])[4]. Chemical bonds in the powders were identified by IR spectroscopy. The surface of the powders and chemical composition was investigated by SEM and EPMA.
