ANTIBACTERIAL CERIUM-CONTAINING GLAZES FOR CERAMIC TILES

The results of research on the production of semi-fritted cerium-containing glazes used for ceramic tiles are presented. A multicomponent raw material mixture based on dolomite, cerium dioxide CeO2, aluminosilicate multicalcium frit and permanent components including feldspar, alumina and clay components (kaolin and refractory clay) is used to produce glazes. The characteristics of the obtained coatings were studied: appearance, technological and physico-chemical properties, including antibacterial properties in relation to the strains of Escherichia coli ATCC 8739 and Staphylococcus aureus ATCC 6538. The influence of temperature parameters on the formation of glaze coatings, as well as their structure and phase composition, has been studied. The effect of grinding of the mixture on the physico-chemical characteristics of glazes has been studied.
