Polycrystalline samples of modifed lead germanate, Pb 4 . 9 5 A 0 . 0 5 Ge 2 . 5 Ti 0 . 5 O 1 1 (A = Ca, Sr, Ba), were prepared using solid-state reaction techniques. X-ray powder diffraction studies of the compounds suggest the formation of single phase materials of trigonal crystal structure at room temperature. Detailed studies of the dielectric constant (ε) and loss (tan δ) of the compounds, both as a function of frequency (2 x 10 2 -10 6 Hz) at room temperature and temperature (from room temperature to 200 o C) at 10, 100 and 1000 kHz, exhibit a ferroelectric diffuse phase transition. The transition temperature is found to decrease with Ba, Sr and Ca doping at the Pb site. The biasing field and temperature dependence of dc electrical conductivity were measured for all the compounds. The nature of the ferroelectric phase transition was checked by measuring the temperature dependence of the polarization.
