    • PROBLEM TO BE SOLVED: To provide a baking tool material having excellent mechanical strength and high adhesiveness of a base material to a thermal-sprayed layer.SOLUTION: The baking tool material includes a thermal-sprayed layer containing at least one to be selected from zirconia or a zirconate on a surface of an alumina-based or alumina-silica-based base material. The baking tool material satisfies the inequalities (1) dp≥750 and (2) vp≥0.007, and the base material thereof has the bending strength of ≥25 MPa, where dp denotes the peak pore diameter (nm) in the pore diameter distribution of the base material measured by the mercury penetration technique, and vp denotes the difference pore volume (ml/g) in the peak pore diameter dp, respectively.
    • 要解决的问题:提供一种具有优异的机械强度和基材对热喷涂层的高粘合性的烘烤工具材料。 解决方案:烘烤工具材料包括在氧化铝基或氧化铝 - 二氧化硅基基材的表面上含有至少一种选自氧化锆或锆酸酯的热喷涂层。 烘焙工具材料满足不等式(1)dp≥750和(2)vp≥0.007,其基材的弯曲强度为≥25MPa,其中dp表示孔径分布中的峰值孔径(nm) 通过水银渗透技术测定的基材,vp分别表示峰值孔径dp的差孔容积(ml / g)。 版权所有(C)2012,JPO&INPIT
