Properties of Materials Obtained by the Sol-Gel Method Based on the System SiO2–CaO–P2O5–TiO2

Abstract

The sol-gel method was used to synthesize thin films based on the system SiO₂–CaO–P₂O₅–TiO₂. Infrared spectroscopy, x-ray phase analysis, and thermal analysis were used to investigate the properties of the material. The thin films were obtained from film-forming solutions (FFS) on substrates comprised of single-crystalline silicon (model substrate) by drawing at the rate 5 mm/sec followed by heat-treatment at 60°C for 20 min and at 600 and 800°C for 1 h. The biological activity was investigated under artificial conditions in the SBF medium. Bioactive material starts to grow when the weight content of titanium oxide in the system reaches 10%.
