Abstract
This invention provides a ceramic powder capable of forming a sintered body having a high density and high ionic conductivity even at a sintering temperature lower than the temperature conventionally used, and provides a battery containing a sintered body of the ceramic powder as a constituent element. The above problem is solved by a ceramic powder containing a garnet-type oxide and compound 1, wherein the garnet-type oxide contains zirconium, lithium, and lanthanum, and compound 1 contains at least one metal element selected from the group consisting of lanthanum, lithium, zirconium, gallium, scandium, yttrium, cerium, aluminum, calcium, magnesium, barium, strontium, niobium, and tantalum.
Claims8
A ceramic powder, comprising:
- a garnet-type oxide comprising a compound represented by the formula Li7-3xGaxLa3Zr2O12, wherein 0.15≤x≤0.35;
- lanthanum oxide;
- and
- lithium gallate,
- wherein a molar ratio of lanthanum to zirconium in the ceramic powder is 1.51 or more and 1.59 or less.
