| Abstract: | Materials syntethis based on oxide system SiO2-P2O5-CaO-MgO was conducted by the sol-gel method. Tetraethyl orthosilicate (TEOS), phosphoric acid (H3PO4), calcium nitrate (Ca(NO3)2・4H2O) and magnesium nitrate (Mg(NO3)2・6H2O) in ethanol (C2H5OH) were used for preparation of solution. Viscosity of the solutions was 1,6-1,8 mm2/s on the first day. On the second day a precipitate was formed in solution. Chemical bonds in the solutions were identified by IR spectroscopy. Powder X-ray diffraction showed at 800°C in the samples fixed phases quartz SiO2, whitlockite (Ca2,589 Mg0,411 )(PO4)2, β-cristobalite high SiO2, stanfieldite Mg3Ca3(PO4)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. |
