MATERIAL FOR THERMAL BARRIER COATING AND ARTICLE
To provide a material for a thermal barrier coating, which can be suitably used for forming a thermal barrier coating having excellent low-thermal conductivity and structural stability.SOLUTION: The material for a thermal barrier coating includes a compound X which is a defective perovskite-type composite oxide having a cationic defect type. A unit cell of the compound X is composed of two octahedrons each having six oxygen atoms. The unit cell has a structure in which two octahedrons are arranged sharing one oxygen atom. In the compound X, the respective central axes of the two octahedrons belonging to adjacent unit cells and adjacent to each other are inclined with respect to each other. A periodic structure in which the octahedrons having different inclinations are alternately arranged is configured with a plurality of the two octahedrons belonging to adjacent unit cells and adjacent to each other. The compound X has a boundary at which a periodicity of the periodic structure changes in its crystal structure.SELECTED DRAWING: Figure 2A
【課題】 低熱伝導性及び構造安定性に優れる遮熱コーティングの形成に好適に用いることができる遮熱コーティング用材料を提供する。【解決手段】 カチオン欠損型の欠陥ペロブスカイト型複合酸化物である化合物Ｘを含み、前記化合物Ｘの単位格子は、それぞれが６つの酸素原子で構成され、かつ１つの酸素原子を共有する２つの八面体が並んだ構造を有しており、前記化合物Ｘにおいて、隣接する単位格子にそれぞれ属し、かつ隣り合う２つの八面体のそれぞれの中心軸は、互いに傾いており、前記隣接する単位格子にそれぞれ属し、かつ隣り合う２つの八面体は、複数並ぶことで、異なる傾きを持つ八面体が交互に並ぶ周期的な構造を構成し、前記化合物Ｘは、その結晶構造中に前記周期的な構造の周期性が変化する境界面を有する遮熱コーティング用材料。【選択図】 図２Ａ
