Abstract
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.about.5 wt. %, preferably 1.about.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.
