Основу сырьевых поликомпонентных композиций составляли алюмосиликатная многокальциевая стеклофритта, доломитовая мука, полевой шпат, глинозем, кварцевый песок, каолин мокрого обогащения и глина огнеупорная. Покрытия получены однократным обжигом на керамической основе керамогранита при температуре 1 200 ± 5 °C скоростным режимом в течение 60 ± 2 мин. Изучены процессы глазурообразования покрытий, установлено влияние составляющих глазурных шихт на декоративно-эстетические характеристики глазурей (цвет, фактура, блеск и белизна). Определены показатели физико-химических свойств покрытий в соответствии с нормативной технической документацией на изделия: температурный коэффициент линейного расширения (ТКЛР), термостойкость, химическая устойчивость, микротвердость, морозостойкость, износостойкость и др. Исследована антибактериальная активность покрытий по отношению к тест-штаммам Escherichia coli ATCC 8739 и Staphylococcus aureus ATCC 6538. </p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of studies on the production of semi-coated glazes with antibacterial activity by introducing variable valence oxides CeO2, WO3, Bi2O3, Fe2O3, MnO2 and MoO3 into their composition. The raw polycomponent compositions were comprised of aluminosilicate multi-calcium glass frit, dolomite powder, feldspar, alumina, quartz sand, wet-enriched kaolin and refractory clay. The coatings were obtained by single firing on a ceramic-based porcelain stoneware at a temperature of 1 200 ± 5 °C in a high-speed mode for 60 ± 2 minutes. The study focused on the processes of glaze formation of coatings and the influence of the components of glaze charges on decorative and aesthetic characteristics of coatings (color, texture, gloss and whiteness). Parameters of physical and chemical properties were determined in accordance with the existing specification for the products, i. e. temperature coefficient of linear expansion, heat resistance, chemical resistance, microhardness, frost resistance, wear resistance, etc. Antibacterial activity of the coatings towards Escherichia coli ATCC 8739 and Staphylococcus aureus ATCC 6538 test strains was studied. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>антибактериальная активность</kwd><kwd>полуфриттованная глазурь</kwd><kwd>температурный коэффициент линейного расширения</kwd><kwd>микротвердость</kwd><kwd>блеск</kwd><kwd>белизна</kwd><kwd>растекаемость</kwd><kwd>термостойкость</kwd><kwd>износостойкость</kwd><kwd>химическая устойчивость</kwd></kwd-group><kwd-group xml:lang="en"><kwd>antibacterial activity</kwd><kwd>semi-coated glaze</kwd><kwd>temperature coefficient of linear expansion</kwd><kwd>microhardness</kwd><kwd>gloss</kwd><kwd>whiteness</kwd><kwd>spreadability</kwd><kwd>heat resistance</kwd><kwd>wear resistance</kwd><kwd>chemical resistance</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Bright, K.
