Abstract

Ba_0.2 Sr_0.8 TiO₃ samples have been fabricated by solid state reaction. The samples were sintered at temperature 900, 1000, and 1100⁰ C for 2 hours. Characterization of sample using XRD. The analysis exibits that the cubic lattice parameter of BST sintered at 900, 1000, and 1100⁰ C are a = b = c respectively 3.913, 3.910, 3.915 nm. The particle sizes and lattice strains of sampel sintered at 900, 1000, and 1100⁰ C respectively 93 nm, 104 nm, 110 nm and 1,58%, 1,51%, 1,49%. Dielectric constant (K) measurements were performed at the range of frequency 0.01 to 10 kHz where the values are maximum at a minimum frequency. The K values for samples sintered at 900, 1000, and 1100⁰ C at minimum frequency are 1388, 3299 and 3870 respectively.
