The expediency of using titanium dioxide in the development of antibacterial glass enamel coatings has been established. A bactericidal powder (filler) based on hydroxyapatite modified with titanium oxide has been synthesized, and its phase composition has been investigated. It was found that the investigated composite glass enamel coatings are characterized by a significant antibacterial and antifungal effect from 70 to 90% with the content of the synthesized inorganic filler from 1 to 5% at the ratio Ti 4+ & nbsp; / & nbsp; (Ti 4+ & nbsp; + & nbsp; Ca 2+ ) equal to 0.04 - 0.07. Il. 3, tab. 1, bibliography: 10 titles.
