Abstract

Abstract:

SiO₂doped barium strontium titanate（Ba_0.65Sr_0.35TiO₃,BST） ceramics（BST+x%SiO₂） were prepared by traditional solidstate reaction method.The effects of SiO₂ doping on the phase,morphology,dielectric properties and electrocaloric effect of BST ceramics were studied.The results showed that doping SiO₂ didn′t change the crystal structure of BST ceramics,but improved the uniformity of grain and the frequency stability of dielectric properties of BST ceramics.With the increase of SiO₂ content,the dielectric constant decreased monotonously,the dielectric dispersion characteristics increased gradually.The doping of SiO₂ was beneficial to improve the electrocaloric performance of BST ceramics.Among them,BST+3% SiO₂ ceramic possessedthe best electrocaloric effect,and the temperature of the maximum electrocaloric adiabatic temperature change （ΔT_max) was 30 ℃.Its ΔT_max and ΔT_max/ΔE were 1.6 ℃ and 8.00×10 ^-7 ℃·m/V respectively,the half-width of the electrocaloric effect（T_span）was about 10 ℃.

Key words: barium strontium titanate, silica, dielectric properties, electrocaloric effect
