Dielectric properties and energy storage density in ZnO-doped Ba0.3Sr0.7TiO3 ceramics

Effects of SrO–B2O3–SiO2 glass additive on densification and energy storage properties of Ba0.4Sr0.6TiO3 ceramics

“…Recently, several additives [10][11][12][13] such as oxides and glasses have been employed to improve the dielectric breakdown strength (BDS) in order to obtain a higher energy storage density. In general, the improvement of BDS can be attributed to the reduction of grain size and pore size, the decrease of porosity, and a more homogeneous microstructure.…”

The effect of glass addition on the ultra-broad temperature stability of BaTiO3–Na0.5Bi0.5TiO3–Nb2O5-based ceramics

“…It can be explained as that Zn 2 þ , Bi 3 þ and B 3 þ of glass incorporate into the BNN matrix. The ionic radius of Zn 2 þ in 12 coordination (0.113 nm) is smaller than that of Ba 2 þ (0.161 nm), and the ionic radius of Zn 2 þ in six coordination (0.074 nm) is larger than that of Ti 4 þ (0.061 nm) [8]. Thus, the Zn 2 þ acts as both donor and acceptor.…”

Structural, dielectric and electrical properties of Zn doped Ba0.8Sr0.2TiO3

“…Also, it is found that Bi doping affects both the maximum dielectric permittivity of BST compound and the dielectric temperature transition [13]. In the temperature range 233K-263K, the addition of ZnO in Ba 0.7 Sr 0.3 TiO 3 system [14] decreases slightly the dielectric constant.…”
