CERAMIC FORMED BODY

摘要

PROBLEM TO BE SOLVED: To improve the adhesion property between a water-repellent layer and an intermediate layer essentially comprising a glaze on the surface of a ceramic formed body with respect to a ceramic formed body to which soiling preventing performance is imparted. SOLUTION: The excellent water repellency and water-repellent durability are obtained by forming hydroxyl groups on the surface of the intermediate layer essentially comprising the glaze 3 containing zirconium silicate 2 and then forming the water-repellent layer.
