PRODUCTION OF CONDUCTIVE CERAMIC

摘要

PURPOSE:To produce a highly dense product having the high electric conductivity of a LaCrO3 composition and capable of being sintered at low temperatures. CONSTITUTION:The method for producing the conductive ceramic comprises adding 0.01-30wt.% of the oxide of the group IIIa element in the periodic table and 0.01-30wt.% of MgO to the powder of a perovskite type composite oxide containing at least La and Cr as metal elements, molding the powder mixture into a prescribed shape and subsequently sintering the molded product in a 1300-1700 deg.C oxidizing atmosphere.
