摘要: Provided is a manufacturing method with which it is possible to convert a mayenite-type compound to an electride, wherein a reducing agent is not required, reaction conditions include a temperature that is lower than that in the related art, and the reaction is performed more quickly in a simple manner, and, additionally, by requiring a lower amount of energy. Provided is a method for manufacturing an electride of mayenite-type compounds, the method being characterized in that a mayenite-type compound is converted to an electride by making a current directly flow through the mayenite-type compound by applying a voltage to the mayenite-type compound in a heating state.

摘要: If a conductive mayenite compound having a large specific surface area is obtained, the usefulness thereof in respective applications is remarkably increased. A conductive mayenite compound powder having a conduction electron density of 1015 cm−3 or more and a specific surface area of 5 m2g−1 or more is produced by: (1) a step for forming a precursor powder by subjecting a mixture of a starting material powder and water to a hydrothermal treatment; (2) a step for forming a mayenite compound powder by heating and dehydrating the precursor powder; (3) a step for forming an activated mayenite compound powder by heating the compound powder in an inert gas atmosphere or in a vacuum; and (4) a step for injecting electrons into the mayenite compound through a reduction treatment by mixing the activated mayenite compound powder with a reducing agent.
