Abstract: Using organic salts of strontium and barium with titanium butoxide as precursors, the solution of Sr -modified BaTiO3 were prepared successfully. The effect of organic acid and the preparing procedures on the properties (such as stickiness, moist - sensitivity, CO2 - sensitivity) of solutions was detected. The results show that the qualified solutions could be prepared by hydrolyzing titanium butoxide in ethyl acetate partially and then mixing the former with the Ba and Sr organic salts (CxH2xCOO-, x = 7 - 8) in the same solvent sufficiently. Using the solutions, Pt/BST/Al capacitor and Si/BST/Al capacitor were prepared. The dielectric constant of BST is about 280 on Pt and 96 on Si. The leakage current of capacitors is lower than 10-8A/cm2 for 0.56 μm BST film.
