Description
Polycrystalline samples of Pb(Li1/4Y1/4X1/2)O3 (where X tungsten and molybdenum) were prepared by solid state reaction technique. Preliminary x-ray studies of these compounds suggest the formation of single phase compound. Detailed dielectric studies (dielectric constant (ε) and dielectric loss (tan δ)) as a function of temperature (-150 degC to 450 degC) and frequency (200 Hz to 10 kHz) suggest that one of these compounds, Pb (Li1/4Y1/4W1/2)O3 undergoes ferroelectric phase transition of diffuse-type, whereas Pb(Li1/4Y1/4Mo1/2)O3 shows a strong dielectric anomaly, relating to ferroparaelectric phase transition at 317 degC.
