SANITARY WARE |
| 摘要 |
Disclosed is a process for producing a sanitary ware. The sanitary ware includes a glaze layer and a photocatalyst layer provided on the glaze layer. The photocatalyst layer is an oxide film including a co-fired product of a precursor of titanium oxide and a precursor of zirconium oxide and contains 65 to 85% by mass of titanium oxide and 15 to 35% by mass of zirconium oxide. The process includes the steps of applying a solution containing at least a precursor of titanium oxide and a precursor of zirconium oxide on a surface of a sanitary ware free from a photocalyst layer, and then firing the coating to form a photocatalyst layer. |
