Title:
METALLIC ELECTROCONDUCTIVE 12Cao·7Al2O3 COMPOUND AND PROCESS FOR PRODUCING THE SAME
Document Type and Number:
WIPO Patent Application WO/2007/060890
Kind Code:
A1
Abstract:
In an electride C12A7 provided by replacing free oxygen in 12Cao·7Al2O3 with
electrons, a material having metallic electroconductivity and an electric conductivity
of more than 5 × 102 S/cm at room temperature could not have been
produced without difficulties. An electride 12Cao·7Al2O3, which
has metallic electroconductivity and has an electric conductivity of more than
5 × 102 S/cm at room temperature, can be produced by heat treating
titanium metal vapor and 12Cao·7Al2O3 single crystal,
sinter or thin film at a temperature above 600ºC and below 1450ºC for
less than 240 hr. Further, thermoelectric field electron release can also be
realized using an electron release chip fabricated from the electride.
