摘要
本研究是关于 Ba(0.70-x)SmxCa0.30TiO3；BSCT（x = 0.000、0.005、0.010、0.015、0.020 和 0.030）陶瓷的介电和铁电特性的研究。样品采用传统的固态反应路线法制备。X 射线衍射分析证实了包晶四边形结构。测量了介电常数 "ε "和正切损耗 "tanδ "的温度范围（30 ℃-150 ℃）和频率范围（100 Hz-100 kHz）。在 30 °C 时，所有样品的 tanδ 值都很小（3%）。居里温度 "Tc "随着 Sm 含量的增加而降低。在 30 °C 的不同电场下记录了 PE 滞后环。x = 0.015 的样品的电场诱导应变值最大。结果表明，制备的样品适用于潜在的致动器和电容器应用。
Synthesis, dielectric and ferroelectric properties in BSCT ceramics
The present work is on the investigation of dielectric and ferroelectric properties of Ba(0.70-x) SmxCa0.30TiO3; BSCT (x = 0.000, 0.005, 0.010, 0.015, 0.020 and 0.030) ceramics. The samples were prepared by the conventional solid-state reaction route method. The perovskite tetragonal structure was confirmed by X-ray diffraction analysis. The dielectric constant ‘ε’ and tangent loss ‘tanδ’ was measured over a temperature range (30 °C–150 °C) and frequency (100 Hz–100 kHz). All the samples show very small value of tanδ (<3 %) at 30 °C. The Curie temperature ‘Tc’ was found to decreases with increase the Sm-content. PE hysteresis loops were recorded at the different electric fields at 30 °C. The maximum value of electric field induced strain was observed for the sample with x = 0.015. The results show that the prepared samples are suitable for potential actuator and capacitor applications.
期刊介绍：
Current Applied Physics (Curr. Appl. Phys.) is a monthly published international journal covering all the fields of applied science investigating the physics of the advanced materials for future applications.
Other areas covered: Experimental and theoretical aspects of advanced materials and devices dealing with synthesis or structural chemistry, physical and electronic properties, photonics, engineering applications, and uniquely pertinent measurement or analytical techniques.
Current Applied Physics, published since 2001, covers physics, chemistry and materials science, including bio-materials, with their engineering aspects. It is a truly interdisciplinary journal opening a forum for scientists of all related fields, a unique point of the journal discriminating it from other worldwide and/or Pacific Rim applied physics journals.
Regular research papers, letters and review articles with contents meeting the scope of the journal will be considered for publication after peer review.
The Journal is owned by the Korean Physical Society.
