Abstract
Fabrication and characterization of Barium Strontium Titanate are studied to determine the electrical properties, the complex capacitance and relative dielectric constant of the material by annealing Ba0.8Sr0.2TiO3 at 600ºC and 650ºC. Samples are made by using the sol-gel method. Characterization of the samples uses Scanning Electron Microscope (SEM) and Impedance Spectroscopy. Results of SEM for samples 600ºC and 650ºC have thickness of 198 nm and 208 nm respectively. Results of impedance spectroscopy can determine the value of the complex capacitance and relative dielectric constant. The complex capacitance value at temperature of 600ºC is 0.0011 Farad and at temperature of 650ºC is 0.0013 Farad. The value of the relative dielectric constant at temperatures of 600ºC and 650ºC are 2.519 and 3.091 respectively
