POROUS CERAMIC BODY, MEMBER FOR ADSORPTION AND METHOD FOR PRODUCING POROUS CERAMIC BODY
PROBLEM TO BE SOLVED: To provide a porous ceramic body which makes color migration inconspicuous, enables moderate visual recognition of deposition of particles, and has comparatively high stability of position detection accuracy using a sensor or the like.SOLUTION: A porous ceramic body is a porous ceramic body obtained by bonding a plurality of particles containing aluminum oxide as a main component through glass, where a lightness index L* in CIE1976 L*a*b*color space by diffused and reflected light treatment of a surface of at least a part thereof is 58 or more and 71 or less, a chromaticness index a* is -1 or more and 3 or less and a chromaticness index b* is -1 or more and 9 or less, and a plurality of dark portions are dispersed and positioned on at least a part of the surface.SELECTED DRAWING: Figure 1
【課題】 色移りが目立ちにくく、パーティクルの付着が適度に視認でき、かつ、センサ等を用いた位置検出精度の安定性が比較的高い多孔質セラミック体を提供する。【解決手段】 本開示の多孔質セラミック体は、酸化アルミニウムを主成分とする複数の粒子がガラスを介して接合された多孔質セラミック体であって、少なくとも一部の表面の拡散反射光処理によるＣＩＥ１９７６Ｌ＊ａ＊ｂ＊色空間における明度指数Ｌ＊が５８以上７１以下であり、クロマティクネス指数ａ＊が−１以上３以下であり、クロマティクネス指数ｂ＊が−１以上９以下であり、前記表面の少なくとも一部に複数の暗色部が分散して位置している。【選択図】 図１
