Title:
METHOD FOR MANUFACTURING ELECTRIDE-FORM MAYENITE COMPOUND
Document Type and Number:
WIPO Patent Application WO/2018/021282
Kind Code:
A1
Abstract:
Provided is a manufacturing method with which it is possible to convert a mayenite compound to an electride form, 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-form mayenite compound, the method being characterized in that a mayenite compound is converted to an electride form by making a current directly flow in the mayenite compound by applying a voltage to the mayenite compound in a heated state.
