AIP Conference Proceedings Vol. 1772. P. 020002-1-020002-6Abstract: Thin films were synthesized by sol-gel method from alcohol film forming solutions (FFS) based on tetraethoxysilane, phosphoric acid, calcium chloride. Concentration of tetrabutoxytitanium was 0.4 and 0.3 M. Thin films were produced on substrates of single crystal silicon (model substrate) by spin-coating with a centrifuge speed of 3000 rev/min, followed by heat treatment at 60 °C for 20 minutes and at 600 °C for 1 h. During the experiment it was found that film with uniform surface may be got on the fifth day after preparation of the solution with a concentration of Ti4+ 0.3 M. For homogeneous material requires heat treatment at 800 °C. The highest bioactivity was observed in the films based on film-forming solution with a concentration of Ti4+ 0.3 M.
