Negative Temperature Coefficient Resistance (NTCR) Ceramic Thermistors: An Industrial Perspective
TL;DR: In this paper, the authors reviewed the application of NTCR thermistors from an industrial perspective and outlined some of the common applications of such thermistors and future challenges, as well as their potential applications in a wide range of applications.
Journal ArticleDOI
Electroceramics for High-Energy Density Capacitors: Current Status and Future Perspectives
Ge Wang,Zhilun Lu,Zhilun Lu,Yong Li,Linhao Li,Hongfen Ji,Antonio Feteira,Di Zhou,Dawei Wang,Dawei Wang,Shujun Zhang,Ian M. Reaney +11 more
TL;DR: In this article, the fundamental principles of energy storage in dielectric capacitors are introduced and a comprehensive review of the state-of-the-art is presented. But the authors do not consider the use of lead-free materials in high-temperature applications, since their toxicity raises concern over their use in consumer applications.
Journal ArticleDOI
Lone-Pair-Induced Covalency as the Cause of Temperature- and Field-Induced Instabilities in Bismuth Sodium Titanate
TL;DR: In this article, a complex-like bonding of the octahedra at the center of the perovskite was determined to be mediated by a loss of hybridization of the 6s2 bismuth lone pair interacting with the oxygen p-orbitals, which triggered both the field-induced phase transition and the loss of macroscopic ferroelectric order at depolarization temperature.
Journal ArticleDOI
Ultrahigh energy storage density lead-free multilayers by controlled electrical homogeneity
Ge Wang,Jinglei Li,Xun Zhang,Zhongming Fan,Fan Yang,Antonio Feteira,Di Zhou,Derek C. Sinclair,Tao Ma,Xiaoli Tan,Dawei Wang,Ian M. Reaney +11 more
TL;DR: In this article, back scattered scanning and transmission electron microscopy combined with energy dispersive X-ray spectroscopy mapping of (0.7 − x)BiFeO3−0.3BaTiO3-xNd(Zn0.5Zr0.10) ceramics revealed a core-shell grain structure which switched from a bright to dark contrast as x increased.
Journal ArticleDOI
Bismuth ferrite-based lead-free ceramics and multilayers with high recoverable energy density
Dawei Wang,Zhongming Fan,Di Zhou,Di Zhou,Amir Khesro,Shunsuke Murakami,Antonio Feteira,Quanliang Zhao,Xiaoli Tan,Ian M. Reaney +9 more
TL;DR: In this paper, a transition from a mixed pseudocubic and R3c structure to a purely pseudo-cubic structure was observed as x increased with the optimum properties obtained for mixed compositions, where the highest energy densities were achieved for BN15F-BT, due to the enhanced breakdown field strength and large maximum polarization.
