| dc.description.abstractEn | Cold-pressed pellets were prepared from a powder mixture of BaTiO3 with 5 mol% of (CaF2 + LiF). The pellets were then air-fired at different temperatures (800, 930, 1000 or 1100 °C) for different times (2, 4 or 8 h). Dielectric measurements were conducted at temperatures in the range 100–450 K with a wide frequency range, 100 Hz–40 MHz. Permittivity, , showed a diffuse ferroelectric–paraelectric phase transition at lower temperatures (263 KTC368 K), where TC is the Curie temperature. In agreement with a non-relaxor ferroelectric behavior, the ferroelectric Curie temperature was frequency-independent. Dielectric dispersion was significant beyond 10 MHz. Ceramics sintered between 930 and 1100 °C are promising candidates for future fabrication of class II capacitors. | |
