ABSTRACT:
A beta alumina sintered body having no tantalum component in an intergranular phase is manufactured by mixing raw materials consisting essentially of 8.0-10.0 wt % of sodium oxide, 3.0-5.5 wt % of magnesium oxide and/or 0.1-2.0 wt % of lithium oxide, 0.01-0.5 wt % of tantalum oxide, and the remainder of aluminum oxide to obtain raw material powders; forming the raw material powders to obtain a formed body; and sintering the formed body.
