<p>A process for manufacturing MgO-based beta "-alumina sintered bodies from a starting powder comprising an MgO-based beta "-alumina as a main ingredient, through shaping and firing, in which process shaped bodies before firing contain 0.3 SIMILAR 5 wt.%, preferably 1 SIMILAR 3 wt.%, of Na aluminate. The resulting sintered bodies are high in density, ionic conductivity and strength and useful for solid electrolytes, for example, of sodium sulfur cells.</p> |
