CERAMIC POWDER MATERIAL, SINTERED BODY, AND BATTERY
To provide a ceramic powder material that can give a sintered body being dense and high in lithium-ion conductivity at a relatively low temperature.SOLUTION: A ceramic powder material contains: a first garnet-type compound containing Li, La, and Zr; and a second garnet-type compound containing Li, La, and Zr and having a composition different from a composition of the first garnet-type compound, in which the first garnet-type compound and the second garnet-type compound are represented by Formula [1] Li7-(3x+y)M1xLa3Zr2-yM2yO12, where M1 is Al or Ga, M2 is Nb or Ta, the first garnet-type compound satisfies 0≤(3x+y)≤0.5, and the second garnet-type compound satisfies 0.5<(3x+y)≤1.5.SELECTED DRAWING: Figure 1
【課題】 比較的低温条件下で、緻密、且つ、リチウムイオン伝導性に優れた焼結体を得ることが可能なセラミックス粉末材料を提供すること。【解決手段】 Ｌｉ、Ｌａ及びＺｒを含有する第１のガーネット型化合物と、Ｌｉ、Ｌａ及びＺｒを含有し、且つ、第１のガーネット型化合物とは組成の異なる第２のガーネット型化合物とを含み、第１のガーネット型化合物、及び、第２のガーネット型化合物は、式［１］Ｌｉ７－（３ｘ＋ｙ）Ｍ１ｘＬａ３Ｚｒ２－ｙＭ２ｙＯ１２で表され、ここで、式［１］において、Ｍ１は、Ａｌ又はＧａであり、Ｍ２は、Ｎｂ又はＴａであり、第１のガーネット型化合物は、０≦（３ｘ＋ｙ）≦０．５を満たし、第２のガーネット型化合物は、０．５＜（３ｘ＋ｙ）≦１．５を満たすセラミックス粉末材料。【選択図】 図１
