A method for producing a conductive mayenite compound sintered body, the (1) calcium oxide and aluminum oxide, 12.6: 6.4~11.7: 7.3 (CaO : mol of terms of Al 2 O 3 Ratio)), (2) a step of preparing a compact including the calcined powder prepared in step (1), and (3) preparation in step (2). Holding the molded body at a temperature in the range of 1280 ° C. to 1350 ° C. in a reducing atmosphere, whereby a conductive mayenite having a relative density of 90% or more and a minimum dimension of 5 mm or more. A method for producing a compound sintered body. |
