ABSTRACT:
A process for producing a complex oxide containing the valuable metal and an alkali (earth) metal salt, which comprising co-milling a mixture of the valuable metal oxide and/or a precursor thereof, or a mixture of a substance containing the valuable metal oxide and/or a precursor thereof, with an alkali (earth) metal salt to a particle size of the valuable metal oxide or a substance containing the oxide, of 10 μm or less, and heating the co-milled product to a temperature of at least 200° C. so as to induce a solid-phase reaction of the valuable metal oxide with an alkali (earth) metal salt.
