Abstract

Ba1-xSrxTiO3(BST) solid solution with x=0.3,0.4 and 0.5 were prepared by sol-gel method. (Ba, Sr) acetate and Titanate isopropoxide were used as a starting material. XRD patterns confirmed the formation of tetragonal perovskite structure and cubic structure.The FESEM images showed that the particles size reduced when strontium concentration increased. Particles size influence on dielectric constant which observed that with decreasing value dielectric constant due to increased frequency and strontium ion Sr+. The high value of dielectric constant observed at low frequencies and reduced concentration of Sr+.
