Garnet-type oxide sintered body and method for producing same
A garnet-type oxide sintered body according to the present invention includes crystal grains composed of a garnet-type oxide containing Li, La and Zr and a grain boundary composition containing boron and silicon and filling gaps between the crystal grains. The oxide sintered body has the characteristics of high density and high ion conductivity. A production method of the sintered body includes a step of providing a precursor material by mixing a garnet-type oxide powder containing Li, La and Zr with a sintering aid; a step of forming the precursor material into a formed body; and a sintering step of sintering the formed body. The sintering aid contains oxygen, boron, silicon and lithium. The oxygen and boron, or the oxygen and silicon, contained in the sintered aid form a compound.
