Synthesis and dielectric properties of BaTi 1−x Zr x O 3 -based ceramic and film materials

The process of formation of BaTi 1-x Zr x O 3 solid solutions (0.2 ≤ × ≤ 0.5) with perovskite structure has been studied. The phase composition, microstructure and electrophysical properties of BaTi 1-x Zr x O 3 ceramic and film materials have been investigated. It has been shown that when zirconium content of ceramic materials is increased, a decrease in permittivity (e) and loss (tan δ) is observed. In this case, the nonlinearity factor (n R ) retains high values (n R = 30-50 %) in relatively weak electric fields (E = 30-60 kV/cm). BaTi 0.6 Zr 0 . 4 O 3 films have been obtained by sol-gel method. The dielectric properties of films in the microwave range have been investigated.
