  • OXIDE SINTERED COMPACT AND SPUTTERING TARGET, AS WELL AS ITS PRODUCTION PROCESSES
    Publication number: 20150014157
    Abstract: The Li-containing transition metal oxide sintered compact of the present invention includes Li and a transition metal, and further includes Al, Si, Zr, Ca, and Y as impurity elements, of which contents are controlled to the following ranges: Al?90 ppm; Si?100 ppm; Zr?100 ppm; Ca?80 ppm; and Y?20 ppm, wherein the sintered compact has a relative density of 95% or higher and a specific resistance of lower than 2×107 ?cm. The present invention makes it possible to stably form Li-containing transition metal oxide thin films useful as the positive electrode thin films of secondary batteries or the like at a high deposition rate without causing abnormal discharge.
