Preparation and characterization of monodisperse Ag nanoparticles doped barium titanate ceramics

Performance and Mechanism of Piezo-Catalytic Degradation of 4-Chlorophenol: Finding of Effective Piezo-Dechlorination

“…36,37 For example, the dielectric constant of BaTiO 3 containing 10% Ag reached as high as 2950, being 1123 higher than that of pure BaTiO 3 . 38 It is well-known that the dielectric constant is an important index characterizing the piezoelectric activity of materials. Therefore, it was reasonably believed that the enhancement of the piezo-catalytic efficiency was dependent on the improvement in its piezoelectric property of t-BaTiO 3 with the deposition of Ag particles.…”

Dielectric properties, microstructure and diffuse transition of Ni-doped Ba(Zr0.2Ti0.8)O3 ceramics

“…Barium titanate (BaTiO 3 ) is the most common ferroelectric oxide in the perovskite ABO 3 structure, which is used as a capacitor because of its high dielectric constant [1][2][3][4]. In order to reduce the dielectric loss at low frequencies, ZrO 2 was doped into BaTiO 3 to form barium zirconate titanate (Ba(Zr x Ti 1−x )O 3 , short for BZT) [5].…”

Effect of Ag on the sintering and dielectric properties behavior of Bi1.5ZnNb1.5O7 ceramics

“…According to the previous reports [14][15][16][17][18][19][20][21][22][23][24][25], metal doping always leads to large dielectric loss. However, in this paper, it is interesting that the dielectric losses of the composites keep at 10 −4 level due to the well densification of the ceramics caused by the small amount of silver doping when the sintering temperature is over 900 • C, which makes these composites a promising candidate for low firing dielectric materials.…”

“…The dielectric properties can be adjusted to have permittivity from 30 to 200 and temperature coefficient of capacitance from +800 to −1300 ppm/ • C [13]. Recently, much attention has been attracted by a second method, which is based on the metal-ceramic composites [14][15][16][17][18][19][20][21]. As the volume fraction of metals or conducting phases in ceramics increases, the permittivity and conductivity increase gradually and when the volume fraction of the conductive powder reaches a critical value, the conductivity as well as permittivity of the composite increases by several orders of magnitude.…”
