FIELD: chemistry.SUBSTANCE: invention relates to field of electronics, namely to methods of obtaining gas-tight composite electrolytes with mixed oxygen-ion and proton conductivity. Claimed is method of obtaining gas-tight ceramics based on cerium oxide and barium cerate by sintering powders with composition 0.3BaCeGdO-0.7CeGdO, synthesised by method of solid-phase synthesis or method of burning nitrates and citric acid. Before sintering 1 mol % of BaCuOis added to powders, which ensures formation of liquid phase of barium cuprate in the process of burning and quick sintering and compression of ceramics at lower temperatures.EFFECT: reduction of temperature of sintering and time of powder exposure time and energy consumption connected with it without deterioration of electric properties of obtained ceramics.2 ex, 1 tbl, 1 dwg |
