Abstract
An antimicrobial ceramic glazing composition contains one or more antimicrobial agents disposed therein. Methods for making and using the glazing composition are disclosed, as well as substrates having a fired antimicrobial glaze thereon. The antimicrobial agents comprise metallic oxides, with a subset of the disclosed combinations exhibiting synergistic effect in fired glazes.
Claims5
A method for manufacturing a glazed ceramic substrate having an antimicrobial property, comprising:
- applying an antimicrobial ceramic glazing composition to a substrate, the glazing composition including an antimicrobial composition comprising:
- a first antimicrobial metal compound consisting of Bi2O3,
- a second antimicrobial metal compound consisting of ZnO, and
- a third antimicrobial metal compound consisting of Ag2CO3,
- wherein the first antimicrobial metal compound is present in the glaze composition at a concentration of about one percent to about four percent, by weight of glaze composition;
- and
- wherein the second antimicrobial metal compound is present in the glaze composition at a concentration of from about one percent to about four percent, by weight of glaze composition;
- and
- wherein the third antimicrobial metal compound is present in the glaze composition at a concentration of from about 0.5 percent to about four percent, by weight of glaze composition;
- and
- firing the glazing composition to transform the glazing composition into a fired glaze layer;
- wherein the fired glazed layer possesses an antimicrobial property.

A glazed ceramic substrate having an antimicrobial property comprising:
- a ceramic substrate having a first substrate surface;
- and
- a fired antimicrobial composition disposed on the first substrate surface;
- wherein the fired antimicrobial composition is a post-fired state of a ceramic glazing composition including:
- a first antimicrobial metal compound consisting of Bi2O3,
- a second antimicrobial metal compound consisting of ZnO, and
- a third antimicrobial metal compound consisting of Ag2CO3,
- wherein the first antimicrobial metal compound is present in the glaze composition at a concentration of about one percent to about four percent, by weight of glaze composition,
- wherein the second antimicrobial metal compound is present in the glaze composition at a concentration of from about one percent to about four percent, by weight of glaze composition, and
- wherein the third antimicrobial metal compound is present in the glaze composition at a concentration of from about 0.5 percent to about four percent, by weight of glaze composition.
7 more elements
A method for manufacturing an antimicrobial ceramic glazing composition, comprising:
- adding, to the ceramic glaze base, an antimicrobial composition that is:
- a first antimicrobial metal compound consisting of Bi2O3, and
- a second antimicrobial metal compound consisting of ZnO,
- a third antimicrobial metal compound consisting of Ag2CO3,
- wherein the first antimicrobial metal compound is present in the glaze composition at a concentration of about one percent to about four percent, by weight of glaze composition;
- and
- wherein the second antimicrobial metal compound is present in the glaze composition at a concentration of from about one percent to about four percent, by weight of glaze composition;
- wherein the third antimicrobial metal compound is present in the glaze composition at a concentration of from about 0.5 percent to about four percent, by weight of glaze composition;
- milling the ceramic glaze base and added antimicrobial composition;
- rehydrating the milled ceramic glaze base;
- and
- optionally, remixing the rehydrated glaze base.
