摘要：

Ceramics sintered at temperatures in the range 1200-1400 degrees C and with composition Ba1-xKx(Ti1-xNbx)O-3 (0.04 less than or equal to x less than or equal to 0.20) show a relaxor ferroelectric behaviour. All the corresponding dielectric characteristics, i.e., diffusivity of the ferroelectric-paraelectric transition, frequency dispersion of epsilon'(r) shift of T-m with frequency deviation from the Curie-Weiss law, are determined. The behaviour is all the more relaxer because the composition deviates from BaTiO3. This study shows the preparation of lead-free relaxer ceramics, which promotes environmental protection.
