ANTIMIKROBIELLE UND PHOTOKATALYTISCHE GLASURZUSAMMENSETZUNG
The invention relates to a glaze composition having an antimicrobial and photocatalytic effect for surface finishing of a ceramic item, which glaze composition comprises at least one silicon compound, at least one aluminium compound, at least one titanium compound and at least one antimicrobial metal compound, wherein the metal of the at least one antimicrobial metal compound is selected from the group consisting of zinc, tin, copper, calcium, strontium, lanthanum, cerium, iron, nickel, vanadium, molybdenum and tungsten. In the glaze composition, the weight ratio of aluminium to silicon is at least 0.3, the proportion of the metal of the at least one antimicrobial metal compound in the glaze composition is at most 20 wt.% and an aqueous slurry of the glaze composition has a pH that deviates by at least 0.2 from pH 7. The invention also relates to a method for coating a ceramic item with the antimicrobially and photocatalytically acting glaze composition and to a coated ceramic item produced according to the method.
