Embodiment 1

[0039]Example 1 (using glassy carbon as the carbon component and microwave irradiation under a nitrogen atmosphere) 0.22 g of mayenite-type compound was mixed with 0.035 g of glassy carbon (Aldrich Company), and the resulting mixture was contained in an ampoule tube (diameter 2.5 cm , length 15cm). Next, the inside of the ampoule tube was replaced with nitrogen so that the oxygen concentration in the tube was less than 1% (v / v), and the tube was sealed. Next, the ampoule tube is placed in the reaction vessel of the microwave generator, and the mixture in the ampoule tube is irradiated with microwaves at a frequency of 2.45 GHz for 20 minutes at a temperature of 800-900° C. by using the magnetron of the generator.

Embodiment 2

[0040] Example 2 (using glassy carbon as a carbon component and performing microwave irradiation under an argon atmosphere)

[0041] The same operation as in Example 1 was performed except that substitution with argon gas was performed instead of nitrogen gas substitution.

Embodiment 3

[0042] Example 3 (using acetylene black as a carbon component and performing microwave irradiation under a nitrogen atmosphere)

[0043] Except having used 0.029g of acetylene black (Strem Chemicals company) instead of glassy carbon, the same operation as Example 1 was performed.

Description

technical field [0001] The invention relates to a method for producing a conductive mayenite compound. Conductive mayenite-type compounds are suitably used in technical fields such as fuel cell materials, hydrogen storage container materials, sensors, electronic devices, and ion emitters as ceramics exhibiting electrical conductivity. Background technique [0002] The mayenite-type compound is a compound derived from cement minerals produced in the Mayen region of Germany, and has a representative crystal framework of 12CaO·7Al 2 o 3 (Hereinafter, it may also be referred to as "C12A7") oxide ion clathrate aluminosilicate. [0003] Regarding conductive mayenite, Patent Document 1 describes a method of producing conductive mayenite by treating a mayenite-type compound with plasma generated from a rare gas. [0004] In addition, Patent Document 2 describes a p-mayenite (Ca 24 A1 28 o 64 4+ 2O 2- ) free oxygen is replaced by hydrogen for hydrogen-displaced mayenite (Ca ...
