实验过程

Equal molar amounts of barium acetate (1.57 g) and strontium acetate (3.51 g) were combined with acetic acid (5.6 ml) and the mixture heated at 85° C. for 1 hour to dissolve the salts. Titanium isopropoxide (3.51 g) was then added to the mixture. The resulting mixture had the desired a Ba:Sr:Ti molar ratio of 1:1:2. Deionized water (18 megohm) was added to achieve a water:titanium isopropoxide molar ratio of 1000:1 and form a barium strontium titanate sol.
