FIELD: metallurgy.
SUBSTANCE: method involves separate dilution of metallic barium and strontium mixed with organic solvent and carboxylising agent for synthesis of carboxyl-containing derivatives of barium and strontium, which are then mixed and combined with titanium alkoxide in stoichiometric ratio of Ba:Sr:Ti=[0.1÷0.9]:[0.9÷0.1]:1 to perform complexing reactions, and after that, the obtained homogeneous solution is diluted with organic solvent. Dilution of metallic barium and strontium and complexing reactions are performed at the temperature of 15÷40°C, and all the operations of the method are performed in dried inert atmosphere.
EFFECT: rather high electrophysical characteristics of ferroelectric films of barium-strontium titanate; excluding occurrence of non-controlled amount of water in the system and increasing stability and service life of film-forming solutions.
