Title Method for preparing electroconductive Mayenite type compound achieved
Abstract

A method for preparing a Mayenite type compound having been imparted with electroconductivity is provided. A method for preparing an electroconductive Mayenite type compound comprises melting a raw material containing Al and at least one selected from the group of Ca and Sr, holding the resulting molten metal in a low oxygen partial pressure atmosphere having an oxygen partial pressure of 10 Pa or less, and then cooling or annealing the metal in a low oxygen partial pressure atmosphere or in the atmosphere into a solid, to thereby replace the oxygen present in a cage by electrons in a high concentration.
