摘要：
The present invention relates to a mayenite-type compound in which a part of Ca of a mayenite-type compound containing Ca, Al and oxygen is substituted by at least one kind of an atom M selected from the group consisting of Be, Mg and Sr, in which the mayenite-type compound has an atom number ratio represented by M/(Ca+M) of from 0.01 to 0.50, and at least a part of free oxygen ions in a mayenite-type crystal structure are substituted by anions of an atom having electron affinity smaller than that of an oxygen atom.
