Energy storage properties in Ba 0.4 Sr 0.6 TiO 3 ceramics with addition of semi-conductive BaO–B 2 O 3 –SiO 2 –Na 2 CO 3 –K 2 CO 3 glass

Relaxor Ferroelectric BaTiO3–Bi(Mg2/3Nb1/3)O3 Ceramics for Energy Storage Application

“…Figure shows the Weibull distribution, which is usually used for the BDS analysis, of the dielectric BDS for BTBMN ceramics with different BMN contents. When m > 1, it indicates that the failure could be analyzed by the Weibull model . The value of the Weibull modulus m was obtained by linear fitting of the experimental data and presented in Fig.…”

Study of the role of porosity on the functional properties of (Ba,Sr)TiO 3 ceramics

“…BaTiO 3 (BT)-based materials are among the most used oxide systems in microelectronics, in particular for tunable elements, pyroelectric, piezoelectric, electro-optic and charge storage applications [1][2][3][4][5][6][7]. BT and its solid solutions are lead-free ferroelectrics with a wide range of permittivity varying from a few hundreds to thousands, depending mainly on the doping level, microstructural characteristics, density and grain size, temperature range and applied field [7][8][9][10][11].…”

The dielectric and ferroelectric properties of (Ba0.5Sr0.5)TiO3-doped (Bi0.5Na0.5)TiO3 lead-free ceramics

“…[1][2][3][4][5][6] However, in the past two or three decades, due to the health and environmental concerns, a variety of Pb-free perovskite ferroelectric materials have attracted a lot of positive attention. [7][8][9][10] Among them, (Bi 1=2 Na 1=2 TiO 3 ) (NBT), [11][12][13][14][15][16] BaTiO 3 (BT), [17][18][19][20][21][22] and (K 0:5 Na 0:5 )NbO 3 (KNN) [23][24][25][26] -based systems therefore have been widely investigated, especially focusing on the compositions near morphotropic phase boundary (MPB) or polymorphic phase transition (PPT) in order to achieve superior dielectric and piezoelectric properties. 2,3 For example, although NBT exhibits high piezoelectric properties and fascinating phase transition behavior, its low depolarization temperature, high ionic conductivity and huge coercive field (E c ) limit its application.…”
