It has been established that the most informative and universal method for determining the biocidal properties of glass coatings is a quantitative method that takes into account the growth rate of biotest microorganisms inoculated into liquid nutrient media. It has been shown that glass-crystalline and glass-composite coatings based on glasses of the Na 2 O - CaO - ZnO - TiO 2 - Al 2 O 3 - P 2 O 5 - B 2 O 3 < / sub> - SiO 2 is determined by the presence of calcium phosphates and zinc titanates in their structure, as well as a bactericidal filler zinc phosphate. The investigated biocidal glass-crystalline and glass-composite coatings can be used to protect enameled steel dishes for various purposes, depending on their inhibitory effect.
