Structural and dielectric properties of Pb1-xBaxMoO4 ceramics

Polycrystalline samples of Pa modified PbMoO4 (Pb1-xBxMoO4(x = 0, 0.05, 0.1 , 0.15)), members of Scheelite structural family, have been prepared by con ventional high- temperature solid-state reaction technique. Preliminary str uctural studies show that the compounds have been formed in single phase at room temperature. Detailed studies of dielectric constant as a function of temperature suggest that the compounds have non-ferroelectric property, bu t contain space charge polarization at high temperature.
