Abstract
PURPOSE:To obtain the thermally stable titled fine powder having large BET specific surface area, by substituting Co or Fe for a part of Ni in a specified perovskite type fine powder. CONSTITUTION:The amount of Co or Fe which substitutes a part of Ni in perovskite type fine powder expressed in formula ANiO3 is regulated to 7.5-35mol.% in terms of Ni. (In formula, A is a rare earth element or a rare earth element whose one part is substituted by alkali earth metal.) By mixing and reacting an aq. soln. of water soluble salts (e.g. chloride) of transition metal such as Ni and rare earth element (and alkali earth metal) in metal mol. ratio of about one, an aq. soln. of alkali agent (e.g. NaOH) in the amt. required for neutralization or more and an aq. soln. of oxidizing agent (e.g. H2O2) in the required amt., a slurry of oxides of each constituent element is obtd. Then, the precursor obtd. by filtering the slurry, by washing, thereafter by deflocculating in water, by adding with 0.02-0.5wt.% an aq. soln. of CoCl2, ZnCl2, MnCl2 or FeCl2, expressed in terms of anhydrous salt, to the targeted perovskite type fine powder, by mixing and thereafter by filtering and drying, is calcined in non-oxidative atmosphere to obtain the titled fine powder having >=5m<2>/g BET specific surface area.
