  • Method for producing conductive mayenite type compound
    Patent number: 10450198
    Abstract: An object of the present invention is to provide a method for producing conductive mayenite, with which a reaction is completed in a short time, an operation can be simplified, the reaction is easily controlled, and the cost of energy can be reduced. The present invention is a method for producing conductive mayenite, characterized by mixing a mayenite type compound with a carbon component, placing the resulting mixture in an airtight container, and irradiating the mixture with a microwave in an inert gas atmosphere or in a vacuum atmosphere to heat the mixture.

  • Method and apparatus of producing organic compound
    Publication number: 20050002485
    Abstract: A method of producing an organic compound, which includes the steps of irradiating a reaction solution with an electromagnetic wave having a wavelength range of 900 MHz to 30 GHz to heat the solution, thereby producing the organic compound, and removing a low-boiling point component produced through the reaction from a reaction system to facilitate the reaction.
