発明の名称 (英語) Method for producing conductive mayenite compound powder NEW
発明の概要(英語) (CN106277000)
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 cm3 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.
