Journal ArticleDOI
Oxygen-vacancy-related relaxation and conduction behavior in (Pb1-xBax)(Zr0.95Ti0.05)O3 ceramics
Tian-Fu Zhang,Xin-Gui Tang,Qiu-Xiang Liu,Sheng-Guo Lu,Yan-Ping Jiang,Xian-Xiong Huang,Qi-Fa Zhou +6 more
TL;DR: In this paper, the authors investigated low-frequency (20 ∼ 2 × 107 Hz) dielectric properties in the temperature region of 25-650°C and found that Ba2+ doping can slightly reduce the phase transition temperature of ferroelectric to paraelectric.
Journal ArticleDOI
Energy-storage properties and high-temperature dielectric relaxation behaviors of relaxor ferroelectric Pb(Mg1/3Nb2/3)O3–PbTiO3 ceramics
TL;DR: In this article, the low-temperature relaxor behavior of (1 − x)Pb(Mg1/3Nb2/3)O3−xPbTiO3 (x = 0, 5, and 10 mol%) ceramics were examined in the temperature range from 120 to 523 K. The value of the relaxation parameter γ = 1.61-1.94 estimated from the linear fit of the modified Curie-Weiss law indicated the relaxor nature.
Journal ArticleDOI
Oxygen-vacancy-related dielectric relaxation behaviours and impedance spectroscopy of Bi(Mg1/2Ti1/2)O3 modified BaTiO3 ferroelectric ceramics
Ming-Ding Li,Xin-Gui Tang,Si-Ming Zeng,Yan-Ping Jiang,Qiu-Xiang Liu,Tian-Fu Zhang,Wen-Hua Li +6 more
TL;DR: In this paper, the authors investigated the correlation of structure, dielectric, ferroelectric and impedance properties of lead-free ferro-electric ceramics and found that Tm and em showed decreasing trend with the increase of BMT content, while P-E loops became slimmer and slimmer.
Journal ArticleDOI
Eco-Friendly Highly Sensitive Transducers Based on a New KNN–NTK–FM Lead-Free Piezoelectric Ceramic for High-Frequency Biomedical Ultrasonic Imaging Applications
Ruimin Chen,Laiming Jiang,Tian-Fu Zhang,Takayuki Matsuoka,Masato Yamazaki,Xuejun Qian,Gengxi Lu,Ahmad Safari,Jianguo Zhu,K. Kirk Shung,Teng Ma,Qifa Zhou +11 more
TL;DR: The results suggest that the KNN–NTK–FM piezoceramic has many attractive properties over other lead-free piezoelectric materials in developing eco-friendly highly sensitive transducers for high-frequency biomedical ultrasonic imaging applications.
Journal ArticleDOI
Enhanced electrocaloric analysis and energy-storage performance of lanthanum modified lead titanate ceramics for potential solid-state refrigeration applications.
Tian-Fu Zhang,Xian-Xiong Huang,Xin-Gui Tang,Yan-Ping Jiang,Qiu-Xiang Liu,Biao Lu,Sheng-Guo Lu +6 more
TL;DR: The giant electrocaloric effect in lanthanum modified lead titanate ceramics is revealed for the first time, and it is shown that reversible adiabatic temperature change is also about 1.67 K, which exceeds many electroCaloric effect values in current direct measured electrocalori studies.
