CERAMIC STRUCTURE AND REFLECTOR MEMBER
PROBLEM TO BE SOLVED: To provide a ceramic structure excellent in adhesion between a substrate and a coating layer, and to provide a reflector member.SOLUTION: A ceramic structure has: a substrate 3 consisting of an aluminium oxide-based ceramic or an aluminium nitride-based ceramic; and a coating layer 4 positioned while brought at least partially into contact with the substrate 3. The coating layer 4 comprises 60 mass% or more of silicon oxide with regard to 100 mass% of the total component consisting of the coating layer 4, barium and potassium. In the coating layer 4, when a portion closer to the substrate 3 is a first region 4a, and a portion farther away from the substrate 3 than the first region 4a is a second region 4b, the first region 4a has a portion that contains a larger amount of barium and potassium than the second region 4b. The reflector member composed of the ceramic structure.SELECTED DRAWING: Figure 2
【課題】基体と被覆層との密着力に優れたセラミック構造体及び反射鏡用部材の提供。【解決手段】酸化アルミニウム質セラミックス又は窒化アルミニウム質セラミックスからなる基体３と、基体３の少なくとも一部に接して位置する被覆層４とを有し、被覆層４は、被覆層４を構成する全成分１００質量％のうち６０質量％以上含む酸化珪素と、バリウム及びカリウムを含み、亦、被覆層４は、基体３に近い部分を第１領域４ａ、第１領域４ａよりも基体３から遠い部分を第２領域４ｂとしたとき、第１領域４ａは、第２領域４ｂよりも前記バリウムおよび前記カリウムを多く含む部分を有しているセラミック構造体及び該セラミック構造体からなる反射鏡用部材。【選択図】図２
