摘要：

The study of the Na0.5B0.5TiO3-K0.5Bi0.5TiO3 (NBT-KBT) system was carried out using X-ray diffraction and dielectric measurements. The limits of rhombohedral and orthorhombic solid solutions were determined, as well as the evolution of their lattice parameters as a function of composition and temperature. Dielectric permittivity measurements in a wide frequency range between 20 and 800 degrees C showed that all materials are ferroelectric at room temperature and exhibit a diffuse, probably second-order phase transition from the ferroelectric to the paraelectric state. Several peculiar compositions showed the best piezoelectric characteristics for this type of ceramic materials.
