    PROBLEM TO BE SOLVED: To provide a production method capable of obtaining a sintered compact of a dense garnet type oxide having a high ion conductivity.SOLUTION: A sintered compact of a garnet type oxide contains crystal grains of a garnet type oxide containing Li, La and Zr, and a grain boundary composition containing boron and silicon filling between the crystal grains. A production method of the sintered compact includes a step of obtaining a precursor by mixing garnet type oxide powder containing Li, La and Zr, and a sintering aid, a step of obtaining a molding by molding the precursor, and a sintering step of sintering the molding. The oxygen and boron or the oxygen and silicon contained in the sintering aid are forming a compound.SELECTED DRAWING: Figure 5

    【課題】緻密でイオン伝導性も高いガーネット型酸化物の焼結体を得ることのできる製造方法を提供する。【解決手段】ＬｉとＬａとＺｒを含むガーネット型酸化物の結晶粒子と、前記結晶粒子と前記結晶粒子の間を埋める、ホウ素及びケイ素を含む粒界組成物と、を含むガーネット型酸化物焼結体。この焼結体の製造方法は、ＬｉとＬａとＺｒを含むガーネット型酸化物粉末と、焼結助剤とを混合して、前駆体を得る工程と、前記前駆体を成型して成型体を得る工程と、前記成形体を焼結する焼結工程と、を含み、前記焼結助剤は、酸素、ホウ素、ケイ素及びリチウムを含み、前記焼結助剤に含まれる、酸素とホウ素又は酸素とケイ素は化合物を形成していることを特徴とする。【選択図】図５
