PROBLEM TO BE SOLVED: To provide a sintered compact having high density and good proton conductivity and also to provide its manufacture by which the sintered compact can be manufactured at a lower sintering temp. than the conventional sintering temp. SOLUTION: This sintered compact is manufactured by adding 0.03 to 1 pts.wt. of at least one oxide selected from oxides of Fe, Co and Ni to 100 pts.wt. of a perovskite multiple oxide represented by the general formula, AB1-x MXO3-a (wherein: A is an element selected from Ca and Sr; B is Zr; M is at least one element selected from Sc, Y, In, Nd, Sm, Gd and Yb; 0<x<=0.5; and a>0). At this time, at least one oxide selected from oxides of Fe, Co and Ni, or at least one substance selected from substances which can be converted into these oxides by heating is added to the perovskite multiple oxide and the resulting material is sintered in an oxygen containing atmosphere to manufacture the objective sintered compact. |
