COMPOSITE OXIDE POWDER, METHOD FOR PRODUCING COMPOSITE OXIDE POWDER, METHOD FOR PRODUCING SOLID ELECTROLYTE OBJECT, AND METHOD FOR PRODUCING LITHIUM ION SECONDARY BATTERY
Provided are a composite oxide powder from which dense solid electrolyte objects having a high ion conductivity can be produced and a method for producing the composite oxide powder. The composite oxide powder is composed of particles comprising lithium (Li), lanthanum (La), zirconium (Zr), and oxygen (O) and having a cubic garnet-type crystal structure, and has a volume particle size distribution in which the 50% diameter (D50) is 1,000 nm or smaller, the composite oxide powder having a pyrochlore phase content of 10 mass % or less.
