Abstract

A method of manufacturing an electrically conductive mayenite compound, includes (a) preparing a body to be processed, the body to be processed including a mayenite compound or a precursor of a mayenite compound; and (b) performing a heat treatment on the body to be processed under a reducing atmosphere including an aluminum compound and carbon monoxide (CO) gas within a range of 1080° C. to 1450° C., the aluminum compound being a compound that emits aluminum oxide gas during the heat treatment on the body to be processed.
