PROCESS FOR PRODUCING AN OXIDE

WIPO Patent Application WO/2010/041558

A1

Provided is a process for producing an oxide which includes an electrically conductive mayenite type compound and has an electron density of at least 1 x 1018/cm3, starting from a combination of a calcium compound and aluminium compound, or a compound which includes calcium and aluminium with a molar ratio of calcium oxide and aluminium oxide as equivlent oxides in the range 9:10 to 14:5, wherein the process for producing an oxide includes a step of heating and holding the starting material at 900-1300°C to produce a calcined powder which includes at least one oxide selected from a group comprising calcium aluminate, calcium oxide and aluminium oxide, and a step of heating and holding the aforementioned calcined powder at at least 1200°C and less than 1415°C, in a reducing atmosphere in an atmosphere of an inert gas with a partial pressure of oxygen of no more than 1000 Pa or in a vacuum atmosphere.
