成果简介	NOVELTY - Invention relates to synthesis of crystalline powders of lead zirconate-titanate (Pb) phases Pb[Zr(x),Ti(1−x)]O3, including alloying additives, and can be used in making functional ceramic materials, including piezoelectric and dielectric for modern radio electronic equipment. Method of producing piezoceramic material based on lead zirconate-titanate phases, including those containing alloying additives, involves making a mixture by mixing precursors (PbO, ZrO2, TiO2, etc.), solid-phase synthesis of ferroelectric phase powders with subsequent pressing and sintering. Into the initial charge containing precursors with impurities in the form of cadmium oxides, and/or nickel, and/or magnesium, and/or cobalt, and/or iron, and/or manganese in an amount of more than 0.2 wt.% of each of the impurities, adding bismuth (III) and titanium (IV) oxides or bismuth (III) oxide in an amount necessary for the formation of phases of the composition Bi(Me0.5Ti0.5)O3, where Me is a double-charged cation of cadmium, or nickel, or magnesium, or cobalt, or BiMeO3, where Me is a triple-charged cation of iron or manganese. USE - Piezoceramics. ADVANTAGE - Technical result of the proposed method, which involves the use of base phases of precursors containing more than 0.2 wt.% of individual impurities, is the production of a piezoceramic material, values of electrophysical parameters of which are not inferior to values of electrophysical parameters of the same material obtained using precursors without impurities. 8 cl, 15 tbl, 8 ex
