Structural and Ferroelectric Properties in Solid Solution
Abstract
The lattice structure, grain structure and temperature dependent dielectric Sr(1-x)CexTi(1-2/3y) MgyO3 (x = 0.05, 0.10, 0.15 and y = 0.05 sintered in 5%H2 and 95%N2 atmosphere) ceramic samples were successfully clarified. The (Sr, Ce, Ti, Mg)O3 show a structure phase transition at SCTM1 from cubic to tetragonal. It is also obvious, that a small A/B-sites doping promoted the grain growth with relaxor ferroelectric like nature. The ε′−T plot, hysteresis loop along with intrinsic ferroelectricity (PUND) clarify the relaxor ferroelectric nature of the ceramics samples. Further, in the temperature span 50 °C and 200 °C, the ceramic samples showed a good frequency and temperature stability, which show its potential in energy storage devices. REFERENCES [1] C. V.
