Abstract :
The process of formation of BaTi1-xZrxO3 solid solutions (0.2 ≤ × ≤ 0.5) with perovskite structure has been studied. The phase composition, microstructure and electrophysical properties of BaTi1-xZrxO3 ceramic and film materials have been investigated. It has been shown that when zirconium content of ceramic materials is increased, a decrease in permittivity (ε) and loss (tan δ) is observed. In this case, the nonlinearity factor (nR) retains high values (nR = 30-50 %) in relatively weak electric fields (E = 30-60 kV/cm). BaTi0.6Zr0.4O3 films have been obtained by sol-gel method. The dielectric properties of films in the microwave range have been investigated.
