Title:
CERAMIC POWDER MATERIAL, METHOD FOR PRODUCING CERAMIC POWDER MATERIAL, AND BATTERY
Document Type and Number:
WIPO Patent Application WO/2021/014905
Kind Code:
A1
Abstract:
One of the purposes of the present invention is to provide a ceramic powder material that makes it possible to obtain, under relatively low-temperature conditions, a dense sintered body having excellent lithium ion conductivity. The present invention relates to a ceramic powder material containing an LLZ-based garnet-type compound represented by Li7-3xAlxLa3Zr2O12 (where x satisfies 0 ≤ x ≤ 0.3), wherein a main phase of a crystal phase undergoes a phase transition from a tetragonal phase to a cubic phase in the process of raising the temperature from 25°C to 1050°C, and the main phase retains the cubic phase even after the temperature is lowered to 25°C.
