Abstract: A sieres of Ba_{1- x}Sr_xZr_Y Ti_{1- Y} O₃(0≤ x ≤0.4, 0< y <0.3) solid solutions was synthesized by soft chemical method below 100 ℃. The XRD and cell parameters component figures of the series of the solid solutions powder demonstrate that the compounds are mutually miscible in the solid solutions. Furthermore, the observation through a TEM showed that the product has a shape of uniform, substantially spherical particles with an average particle size of 60 nm in diameter. The result of prepared ceramics shows that after being adulterated with Sr²⁺ and Zr⁴⁺ in pure BaTiO₃ phase, the dielectric constant was increased eight times at room temperature, while the dielectric loss was decreased three times.
