Synthesis and properties of materials based on SiO2-CaO-P2O5-TiO2 for biomedical usage

Thin films of film-forming solutions based on calcium chloride, tetraethoxysilane, tetrabutoxytitanium, and phosphoric acid have been synthesized in the paper. Thin films were obtained from film-forming solutions on single-crystal silicon substrates (model substrate) by centrifugation at a rotation speed of 3000 revolutions/min. Followed by heat treatment at 60 ° C for 20 minutes and at 600 and 800 °C for 1 hour. The solutions are suitable for obtaining uniform films up to 5 days. The properties of the material were investigated by the methods of infrared spectroscopy, X-ray phase analysis, and thermal analysis. Biological activity was studied under artificial conditions in the simulation body fluid medium. With an increase in the weight content of titanium oxide in the system up to 10%, the bioactivity of the material increases.
