FIELD: technological processes.
SUBSTANCE: invention relates to high-density solid-oxide proton-conducting materials based on lanthanum nitrate, which can be used as electrolytes for medium-temperature electrochemical devices, including solid-oxide fuel cells, sensors and electrolyzers. Material is a doped zinc or magnesium lanthanum nitrate composition: LaY1–xMxO3–δ, where M = Zn, Mg, and x = 0.01–0.1.
EFFECT: invention allows to reduce the temperature and duration of sintering the resulting high-density solid-oxide proton-conducting material.
