The BCTG exhibits interesting ferroelectric and dielectric properties. The XRD analysis showed that 20 at.% of Ge doping can be fully incorporated into the perovskite lattice of Ba 1Àx Ca x TiO 3 . Dielectric properties revealed that the BCTG ceramic undergone a second order phase transition type at around 120°C independently of the used frequency and behaves as displacive ferroelectric. Ferroelectric investigation showed that P-E hysteresis loop could be obtained at low applied electrical field. The BCTG compound may be highly promising for applications as lead-free ferroelectric materials to reduce environmental damages.
