    摘要： In a solid solution system of Al2O3 and CAO or SrO, it has been difficult to obtain a material having a high electrical conductivity (>10−4 S·cm−) at room temperature. A compound is provided in which electrons at a high concentration are introduced into a 12CaO.7Al2O3 compound, a 12SrO.7Al2O3 compound, or a mixed crystal compound containing 12CaO.7Al2O3 and 12SrO.7Al2O3.

When a single crystal or a hydrostatic pressure press molded material of a fine powder thereof is held at approximately 700° C. in an alkaline metal vapor or an alkaline earth metal vapor, melt of a hydrostatic pressure press molded material of a powder is held at approximately 1,600° C. in a carbon crucible, followed by slow cooling for solidification, or a thin film of the compound held at approximately 600° C. is implanted with rare gas ions, a great number of the free oxygen ions can be substituted with electrons.

The C12A7 compound is heat-treated to clathrate OH− ions at a concentration of 2×1019 cm−3 or less, and On− at a high concentration of more than 2×1019 cm−3. The compound can reversibly clathrate or release On− ion radicals through the elevation or lowering of the temperature thereof in a temperature range of 300 to 850° C.
