Abstract
In an electride C12A7 provided by replacing free oxygen in 12CaO.7AlOwith electrons, a material having metallic electroconductivity and an electric conductivity of more than 5×10S/cm at room temperature could not have been produced without difficulties. An electride 12CaO.7AlO, which has metallic electroconductivity and has an electric conductivity of more than 5×10S/cm at room temperature, can be produced by heat-treating titanium metal vapor and 12CaO.7AlOsingle crystal, sinter, or thin film at a temperature above 600° C. and below 1,450° C. for less than 240 hours. Further, thermoelectric field electron release can also be realized using an electron release chip fabricated from the electride.
