Abstract
Official abstract text for this publication.
A biocidal additive package comprises at least one metal or metal containing compound selected from the group consisting of Cu 2 O, Cu(OH) 2 , Cu, CuO 3 , Cu 2 O 3 , and a combination thereof, and at least one non-copper metal or non-copper containing metal compound. Non-limiting examples of non-copper metal and non-copper containing metal compounds are Ag, Ag 2 O, Bi, Bi 2 O 3 , Zn, ZnO, or a combination thereof. A biocidal ceramic glaze layer and an article comprising a biocidal ceramic glaze layer are provided. Also provided is a method of affixing a biocidal ceramic glaze to a substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A biocidal additive package comprising: at least one metal or metal containing compound selected from the group consisting of Cu 2 O, Cu(OH) 2 , Cu, CuO 3 , Cu 2 O 3 , and a combination thereof, and BaCO 3 . 2. A ceramic glaze layer comprising: at least one metal or metal containing compound selected from the group consisting of Cu 2 O, Cu(OH) 2 , Cu, CuO 3 , Cu 2 O 3 , and a combination thereof, and BaCO 3 . 3. The ceramic glaze layer according to claim 2 , wherein the BaCO 3 is present in a ceramic glaze base in a range of at least 0.1 weight %. 4. The ceramic glaze layer according to claim 2 , wherein the metallic copper or copper-containing metal compound is present in a ceramic glaze base in a range of 1 weight % to 10 weight %. 5. A biocidal ceramic article comprising: a substrate and a ceramic glaze layer on the substrate, wherein the ceramic glaze layer comprises at least one metal or metal containing compound selected from the group consisting of Cu 2 O, Cu(OH) 2 , Cu, CuO 3 , Cu 2 O 3 , and a combination thereof, and BaCO 3 . 6. The biocidal ceramic article according to claim 5 , wherein the substrate is a ceramic substrate. 7. The biocidal ceramic article according to claim 5 , wherein the ceramic glaze layer is a fired or cured ceramic glaze layer. 8. A method of affixing a biocidal ceramic glaze to a substrate comprising: providing a biocidal ceramic glazing composition having one or more biocidal agents disposed therein, applying the biocidal ceramic glazing composition to a substrate having a surface, wherein the biocidal ceramic glazing composition comprises at least one metal or metal containing compound selected from the group consisting of Cu 2 O, Cu(OH) 2 , Cu, CuO 3 , Cu 2 O 3 , and a combination thereof, and BaCO 3 . 9. The method according to claim 8 , wherein the biocidal ceramic glazing composition is applied to a fired glaze layer on the surface of the substrate. 10. The method according to claim 8 , the biocidal ceramic glazing composition is applied to an unfired glaze layer on the surface of the substrate.
