Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing an electride of mayenite-type compounds, the method comprising: converting a mayenite-type compound 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. 2. The method for manufacturing an electride of mayenite-type compounds according to claim 1 , wherein the voltage is applied until an electrical resistivity of the mayenite-type compound becomes 1.0×10 5 Ω·cm or less. 3. The method for manufacturing an electride of mayenite-type compounds according to claim 1 , wherein a positive electrode and a negative electrode are provided to the mayenite-type compound to making a current directly flow. 4. The method for manufacturing an electride of mayenite-type compounds according to claim 1 , wherein the mayenite-type compound is converted to an electride under an inert gas atmosphere. 5. The method for manufacturing an electride of mayenite-type compounds according to claim 1 , wherein an electron concentration of the electride of mayenite-type compounds is 1.0×10 20 /cm 3 or more.
