PROBLEM TO BE SOLVED: To obtain electroconductive ceramics capable of enhancing the sinterability and carrying out the densification at a low temperature without deteriorating excellent electroconductivity possessed by LaCrO3 . SOLUTION: The electroconductive ceramics comprise La, Cr and Mg as metallic elements and contain a perovskite type compound oxide as a main crystal phase and Ca and at least one of Y, Yb, Sc, Sm, Nd, Dy and Pr in respective amounts of 0.01-2.0 pts.wt., based on 100 pts.wt. perovskite type compound oxide and expressed in terms of oxides. |
