| 内容記述 | We investigated the effect of excess Na contents in precursor on the property of Na2Zn2TeO6 (NZTO) solid electrolyte synthesized via a conventional solid state reaction method. In XRD analysis, we confirmed that P2-type layered NZTO phase were mainly formed in all sintered samples, but the samples without excess Na addition in the precursor contained the secondary phases, which could be formed by Na volatilization during high temperature processing. The relative densities of sintered NZTO samples were in the range from 80 to 87% and decreased with increasing the excess Na contents in the precursor. The samples with 0 and 3% excess Na showed the total (grain + grain boundary) conductivity far below 10−4 S cm−1 at room temperature, but the conductivity for the samples with 7 and 10% excess Na was well above 10−4 S cm−1. The sample with 7% excess Na in precursor showed the highest conductivity of 3.8 × 10−4 S cm−1 at room temperature and low activation energy of 0.25 eV. | |||||
