METAL OXYNITRIDE POWDER AND METAL OXYNITRIDE FIRED BODY
To provide a metal oxynitride powder having a structure where electron transporting passages are properly cut in a specific direction.SOLUTION: The metal oxynitride powder has a perovskite structure and contains a plurality of metal oxynitride particles of a composition formula represented by SrTaON, wherein: x is larger than 0 and lower than or equal to 0.31; the metal oxynitride particle has a first structure belonging to a space group of I4/mcm and a second structure which is a structure having the structure belonging to the space group of I4/mmm being divided equally with a face perpendicular to a c axis of the structure; at a boundary of the first structure and the second structure, the c axis of the first structure and the second structure are common; in the c axis direction, the first structure and the second structure are bonded to each other; and among layers perpendicular to the c axis constituting the second structure, at least one layer is a layer not containing nitrogen. By firing the metal oxynitride powder, a metal oxynitride fired body having the first structure and second structure being maintained is obtained.SELECTED DRAWING: Figure 8
【課題】特定の方向に電子の移動経路が適度に切断された構造を有する金属酸窒化物粉末を提供すること。【解決手段】ペロブスカイト構造を有し、組成式Ｓｒ１＋ｘＴａＯ２＋ｘＮで表される金属酸窒化物粒子を複数含む金属酸窒化物粉末であって、ｘが０より大きく０．３１以下であり、金属酸窒化物粒子は、空間群Ｉ４／ｍｃｍに属する第１構造と、空間群Ｉ４／ｍｍｍに属する構造を当該構造のｃ軸に垂直な面で等分した構造である第２構造と、を有し、第１構造と第２構造との境界において、第１構造および第２構造のｃ軸が共有され、ｃ軸方向において、第１構造と第２構造とが結合しており、第２構造を構成するｃ軸に垂直な層のうち、少なくとも１つの層が窒素を含まない層である金属酸窒化物粉末である。当該金属酸窒化物粉末を焼成することにより上記第１構造および第２構造が維持された金属酸窒化物焼成体が得られる。【選択図】図８
