CERAMIC GLAZE HAVING ANTIMICROBIAL PROPERTY

摘要

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.

1. An antimicrobial ceramic glazing composition, comprising:
a ceramic glaze base adapted to be fired at a firing temperature of from at least about 1062° C.; and a synergistic antimicrobial composition including a first antimicrobial agent and a second antimicrobial agent, the antimicrobial composition being one of:
2% Ag2CO3+2% Bi2O3,2% Ag2CO3+2% CuO,2% Ag2CO3+4% SnO2,2% Ag2CO3+2% ZnO,2% Ag2CO3+4% ZnO,2% Bi2O3+2% CuO,2% Bi2O3+4% CuO,2% CuO+4% Ag2CO3,2% CuO+4% SnO2,2% CuO+2% TiO2,2% CuO+4% TiO2,2% CuO+4% ZnO,2% SnO2+4% Ag2CO3,2% SnO2+4% CuO,2% TiO2+4% Ag2CO3,2% TiO2+4% CuO,2% ZnO+4% Ag2CO3, or2% ZnO+4% CuO; wherein the glazing composition is adapted to possess a durable antimicrobial property after a conventional firing process at the firing temperature.
