Ceramic additive formulation and method of making
A method of making a ceramic glaze formulation having an antimicrobial property for use with a ceramic article. The method comprises fritting an antimicrobial formulation in a flux frit, providing least one unfritted antimicrobial component, providing a silver carrier in a glass matrix, and combining the flux frit, the at least one unfritted component, and the silver carrier in the glass matrix to form the ceramic glaze formulation. The silver carrier is combined at an addition rate based on a dry weight basis of the ceramic glaze formulation. A ceramic glaze additive formulation and ceramic glazed article are also provided.
1. A ceramic glaze additive formulation comprising:
0.1% to 1% by weight of silver carrier;
12% to 21% by weight of Bi 2 O 3 ;
29% to 37% by weight of ZnO; and
45% to 55% by weight of flux frit;
wherein a weight percentage is based upon the weight of the ceramic glaze additive formulation.
2. A ceramic glazed article comprising the ceramic glaze additive formulation of claim 1 applied on a surface of the ceramic article.
3. A ceramic glaze additive formulation comprising:
5% to 15% by weight of silver carrier;
80% to 90% by weight of ZnO; and
1% to 10% by weight of flux frit;
wherein a weight percentage is based upon the weight of the ceramic glaze additive formulation.
4. A ceramic glazed article comprising the ceramic glaze additive formulation of claim 3 applied on a surface of the ceramic article.
