A Ternary System PbO-TiO2-ZrO2

Abstract
In a ternary system PbO-TiO2-ZrO2, specimens of various compositions are prepared by solid state reactions and analyzed by x-ray diffraction method. A reaction diagram of this system is proposed. Some compounds ZrTiO4, PbTiO3, PbZrO3 and solid solutions Pb(Ti-Zr)O3 were early known, and no other compounds are found here. Single phases of perovskite-type structure extend over wider ranges around Pb(Ti-Zr)O3 than expected. Some ceramic specimens among them belonging to these phases are examined as to their dielectric and piezoelectric properties.
