Title:
A manufacturing method of a lithium lantern titanium oxidation thing sintered compact
Document Type and Number:
Japanese Patent JP5998411
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of a lithium lanthanum titanium oxide sintered body in which a lithium ion conductivity at a measured temperature of 27°C is at least 3.0×10Scm.SOLUTION: A production method of a lithium lanthanum titanium oxide sintered body includes: a mixing process in which a titanium raw material, a lithium raw material and a lanthanum raw material are comminuted and mixed; a calcination process in which the mixed powder obtained by the mixing process is calcined; a comminution process in which a calcined product obtained by the calcination process is comminuted; a molding process in which the powder obtained by the comminution process is molded; and a sintering process in which a molded body obtained by the molding process is sintered, wherein a concentration of Cl in the mixed powder is at most 550 ppm.
