Abstract
The paper presents the results of measurements of a solid solution (1-x)K0.5Bi0.5TiO3-xSrTiO3 (KBT-ST) ceramics with (for) x=0.001 for two different sintering temperatures (cases of times sintering): (1) at temperature 1303K for 6 hours (KBT-ST 1) and (2) at temperature 1313K for 6 hours (KBT-ST 2). In both cases, the X-ray diffraction study demonstrated the perovskite structure with a small amount of the second phase. Microstructure research with SEM allowed to observe well-developed grains for both obtained samples. Optical studies using Raman spectroscopy showed that the obtained samples have a local structure consistent with the base material K0.5Bi0.5TiO3 (KBT). Dielectric study of these solid solution ceramics were taken in the temperature range from 293K to 873K and in the frequency range from 10 kHz to 1 MHz. These measurements allowed to observe in both cases a broad maximum similar to that for the base KBT ceramics. It has been observed that if the sintering temperature increase up to 1313K it causes a double increase in the dielectric constant and (it doubles the dielectric constant value and causes) the appearance of additional anomaly on the ε(T) curve at temperature approximately Td=521K.
