[en] To increase labour productivity by 25-80%, to ensure stoichiomet stoichiomety of composition with +-0.01 accuracy and to liquidate lead-containing wastes a new method of the obtaining of powder materials on the basis of lead zirconate-titanate is suggested. It differs from the existing one by the following: solutions of titanium and zirconium salts are mixed preliminarily and after introduction of crystalline oxalic acid solutions of lead salt, modifying additions and ammonia are gradually added. After ammonia introduction pH of the medium is maintained within 9.0-9.5. The method suggested permits to increase the product yield up to approximately 100%, to obtain high-purity substance with particle size < 1 μm
