PURPOSE:To produce the titled easily sinterable fine powder having high purity and uniform composition, by reacting an acidic solution or suspension containing various kinds of metals with a basic gas, calcining the resultant precipitate, mixing with a lead compound powder, and calcining the mixture. CONSTITUTION:An acidic solution or suspension containing various kinds of metals constituting the objective lead-containing oxide is blasted with the vapor or a basic substance (e.g. ammonia) having a boiling point of <=100 deg.C under normal pressure, and the precipitate produced by the reaction is separated by filtration, washed with ethanol, acetone, etc. to remove impurities, and calcined at 450-1,200 deg.C to obtain powder. The powder is mixed with a lead compound powder such as PbO, Pb3O4, etc., and calcined at 600-1,000 deg.C.
