CERAMIC POWDER MATERIAL, METHOD FOR PRODUCING CERAMIC POWDER MATERIAL, AND BATTERY
To provide a ceramic powder material capable of obtaining a sintered compact having high density and excellent lithium ion conductivity under a relatively low temperature condition.SOLUTION: Provided is a ceramic powder material which contains a LLZ-based garnet-type compound represented by Li7-3xAlxLa3Zr2O12 (where x satisfies 0≤x≤0.3), in which a main phase of a crystal phase changes from a tetragonal phase to a cubic phase in the process of heating from 25°C to 1050°C and the main phase remains the cubic phase even after cooling to 25°C.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】 Ｌｉ７−３ｘＡｌｘＬａ３Ｚｒ２Ｏ１２（ただし、ｘは、０≦ｘ≦０．３を満たす）で示されるＬＬＺ系ガーネット型化合物を含み、２５℃から１０５０℃まで昇温する過程で、結晶相の主相が正方晶相から立方晶相に相転移し、２５℃まで降温した後も主相が立方晶相であるセラミックス粉末材料。【選択図】 図１
