A method of manufacturing an electrical conductive mayenite compound, including, (1) a step of preparing a calcinated powder including calcium oxide and aluminum oxide at a ratio of 13: 6 to 11: 8 (based on molar ratio as converted to CaO: Al 2 O 3 ), and (2) a step of placing a body to be processed including the calcinated powder prepared in the step (1) in the presence of carbon monoxide gas and aluminum vapor supplied from the aluminum source without contacting the aluminum source, and holding the body to be processed at a temperature range of 1220 °C to 1350 °C under reducing atmosphere. |
