Electro-caloric effect in relaxor and ferroelectric compositions of Pb(Mg(1−x)/3Nb2(1−x)/3Zrx)O3 ceramics

Relaxor Behavior and Dielectric Properties of Bi(Zn2/3Nb1/3)O3-Modified BaTiO3 Ceramics

“…1,2 A series of capacitors in microelectronics with notable electric properties are lead-based perovskite materials, such as Pb(Mg,Nb)O 3 (PMN), Pb(Zr,Ti)O 3 (PZT), and Pb(Sc,Ta)O 3 (PST), and the derived compounds. [3][4][5][6][7] The researchers confirmed that the chemistry of Pb plays an important role in achieving excellent properties of Pb-based ferroelectrics ceramics. 8,9 However, due to restriction of the leadbased ferroelectric materials, researchers frequently explore the environmentally friendly leadfree systems.…”

Thermally Stable BaTiO3‐Bi(Mg2/3Nb1/3)O3 Solid Solution with High Relative Permittivity in a Broad Temperature Usage Range

“…However, in extreme environments, such as aerospace, the working temperature limit of devices is required to be higher than 200°C, which exceeds the scope of X9R . Although most PbTiO 3 ‐based relaxor materials may offer high operating temperatures, this is at the expense of environment . Besides, in order to satisfy the development of devices toward greater miniaturization and c, high permittivity is also urgently required …”

“…2,3 Although most PbTiO 3 -based relaxor materials may offer high operating temperatures, this is at the expense of environment. [4][5][6][7][8] Besides, in order to satisfy the development of devices toward greater miniaturization and c, high permittivity is also urgently required. 9 As one of lead-free materials, BaTiO 3 (BT) has been extensively studied and applied to capacitors for many years owing to its good dielectric properties.…”

Characterization of Pb(In1/2Nb1/2)O3–PbTiO3 ferroelectric crystals grown by top-seeded solution growth method

“…formula due to their excellent piezoelectric and electromechanical properties in the compositions close to or within the morphotropic phase boundary (MPB) compared with the conventional piezoelectric ceramics (1 À x)PbZrO 3 -xPbTiO 3 (PZT) [1][2][3][4][5][6]. Such ferroelectric materials are of great interests for their potential application in the electromechanical field, for example, the piezoelectric actuators, transducers, sensors and so on [2,3,[7][8][9][10].…”
