Abstract

Barium Strontium Titanate (Ba1-xSrxTiO3) or BST was prepared by solid state reaction method. Raw materials are BaCO3, SrCO3, and TiO2. Those materials are mixed for 8?h, pressed, and sintered at temperature 1200°C for 2?h. Mole composition of Sr (x) was varied to study its influences on structural, morphological, and electrical properties of BST. Variation of (x) are x = 0; x = 0.1; and x = 0.5. XRD patterns showed a single phase of BST, which mean that mixture of raw materials was homogenous. Crystal structure was influenced by x. BaTiO3 and Ba0.9Ti0.1TiO3 have tetragonal crystal structure, while Ba0.5Sr0.5TiO3 is cubic. The diffraction angle shifted to right side (angle larger) as the increases of x. Crystalline size of BaTiO3, Ba0.9Sr0.1TiO3, and Ba0.5Sr0.5TiO3 are 38.13?nm; 38.62?nm; and 37.13?nm, respectively. SEM images showed that there are still of pores which were influenced by x. Ba0.9Sr0.1TiO3 has densest surface (pores are few and small in size). Sawyer Tower circuit showed that BaTiO3 and Ba0.9Sr0.1 TiO3 is ferroelectric, while Ba0.5Sr0.5TiO3 is paraelectric. The dielectric constants of BaTiO3, Ba0.9Sr0.1TiO3 and Ba0.5Sr0.5TiO3 at frequency of 1?KHz are 156; 196; and 83, respectively. Ba0.9Sr0.1TiO3 has relatively highest dielectric constant. It is considered that Ba0.9Sr0.1TiO3 has densest surface.
