摘要：

Relative permittivity studies of ceramics with a variety of compositions in the BaTiO3-BaZrO3-CaTiO3 system showed some of them to be ferroelectric relaxors at temperatures close to 295 K. Such a favourable effect is due to the Ca2+ for Ba2+ cationic substitution. In addition a spontaneous classical ferroelectric-relaxor ferroelectric transition was evidenced. Some of these new compositions are of interest for applications(dielectrics for capacitors, actuators) since they are environmentally friendly.
