SANITARY WARE HAVING PHOTOCATALYST LAYER
PROBLEM TO BE SOLVED: To provide a sanitary ware having a photocatalyst layer excellent in durability even in an environment where the photocatalyst layer is alternately exposed to an acid and an alkali.SOLUTION: There is provided a sanitary ware which comprises a glaze layer, an intermediate layer provided on the glaze layer and a photocatalyst layer provided on the intermediate layer, wherein the photocatalyst layer comprises titanium oxide and zirconium oxide, the intermediate layer is formed with a composition comprising 98 to 85 mass% of silica and 2 to 15 mass% of titanium oxide and/or zirconium oxide, respectively, thus enabling durability of the photocatalyst layer to be improved significantly. Particularly, the photocatalyst layer has durability even against repeated washing under different conditions of liquid properties such as acidity and alkalinity.SELECTED DRAWING: None
【課題】 酸とアルカリとに交互に曝される環境にあっても、耐久性に優れた光触媒層を有する衛生陶器の提供。【解決手段】 釉薬層と、この釉薬層上に設けられた中間層と、この中間層上に設けられた光触媒層とを備えてなる衛生陶器において、光触媒層が酸化チタンと酸化ジルコニウムとを含んでなり、中間層を、シリカと、酸化チタンおよび／または酸化ジルコニウムとを、それぞれ９８質量％〜８５質量％、および２質量％〜１５質量％含んでなる組成とすることで、光触媒層の耐久性を大きく改善することができる。特に、酸とアルカリという液性の異なる条件下での繰り返しの洗浄に対しても耐久性を備える。【選択図】 なし
