MANUFACTURING METHOD OF SINTERED BODY, AND SINTERED BODY
To provide a manufacturing method of a porous sintered body having conductivity degradation suppressed, and a sintered body.SOLUTION: A manufacturing method of a sintered body includes a precursor manufacturing step for burning powder obtained by mixing lithium hydroxide and basic material powder of a garnet type oxide containing at least Li, La, and Zr and having an average particle size in the range of 0.1 μm or more and 5 μm or less to synthesize precursor powder not sintered yet and a molding and sintering step for molding the precursor powder as it is or after added with a pore-forming agent and sintering the obtained molded article at a temperature of 900°C or lower to manufacture a sintered body having a void of 8 vol.% or more.SELECTED DRAWING: None
【課題】多孔性を有し、伝導度の低下をより抑制する焼結体の製造方法及び焼結体を提供する。【解決手段】焼結体の製造方法は、平均粒径が０．１μｍ以上５μｍ以下の範囲でありＬｉとＬａとＺｒと少なくとも含むガーネット型酸化物の母材粉末と、水酸化リチウムとを混合して得られた粉末を焼成して未焼結の前駆体粉末を合成する前駆体製造工程と、前駆体粉末をそのまま成形するか又は前駆体粉末に造孔材を添加して成形し得られた成形体を９００℃以下の温度で焼結させ空隙を８体積％以上有する焼結体を得る成形焼結工程と、を含む。【選択図】なし
