Synthesis and dielectric and nonlinear properties of BaTi1 − xZrxO3 ceramics

We have studied the formation of BaTi1 − x Zr x O3 solid solutions with the perovskite structure. The phase composition, microstructure, and electrical properties of the BaTi1 − x Zr x O3 materials have been investigated. The results demonstrate that their dielectric permittivity (ɛ) and loss tangent (tan δ) decrease with increasing zirconium content. At the same time, their nonlinearity coefficient (n R ) remains large (n R = 30–50%) in relatively low fields (E = 30–50 kV/cm). The present data suggest that the materials studied here are potentially attractive for use in creating nonlinear devices of modern microelectronics.
