    Abstract

    Barium Strontium Titanate sample preparation (BaxSr1-xTiO3) for x <0.5 and Strontium Titanate has been carried out using solid state reaction method. Parameters varied in this research is a comparison the number of moles of Ba and Sr are 40:60, 30:70, 20:80, 10:90, and 00:100, and the variation of sintering temperature 1000oC and 1100oC. Characterization of samples was performed using equipment of X-Ray Diffractometer (XRD) to determine the level of crystal form and crystal size of the sample. The more of the Sr composition causes the crystal size is getting larger and lattice parameter getting smaller. Morphology BaxSr1-xTiO3 and Strontium Titanate was tested with instruments of Scanning Electron Microscopy (SEM), a growing number of moles of Sr composition causes the crystal grain size became bigger. Sawyer tower circuit was to got a hysteresis curve. The Tests using the equipment of RLC meter is used to determine the dielectric constant, the measurement is done on the frequency range 1 kHz to 100 kHz. The higher the sintering temperature resulting intensity values, the crystal size and crystallinity, and the grain size getting bigger and dielectric constant value be increase. The dielectric constant (K) is the highest in temperature 1100oC with a thickness of 0.004 m, on the mole of SrTiO3 composition is equal 442. Keywords: Barium Strontium Titanate (BST), Strontium Titanate, Solid State Reaction Method, Dielectric Constant.
