Abstract: The sol-gel chemical preparation method has been applied in producing (Ba0.8 Sr0.2 TiO3 ) solution. The main precursor materials are barium acetate and strontium acetate powder. Acetic acid also has been used as a solvent while titanium Isopropoxide and 2-Methoxyethanol are applied as stabilizer. Annealing process has been used for crystallization of thin films ceramic material. These thin films sample are characterized using X-ray Diffraction for crystalline structure and atomic force microscopy and scanning electron microscopy for microstructure analysis.
