FIELD: technology of high-temperature superconductive ceramic. SUBSTANCE: powder mixture of bismuth, strontium, calcium and copper compounds is annealed firstly at 770-800 C, then at 800-830 C, ground, pressed and annealed in the air at 850 ± 10°C for at least 10 h. Articles were subjected for hot pressing at 930-980 C under pressure 0.1-0.5 GPa for 1-5 h. Use of proposed method ensures to make single-phase solid samples showing high superconductive parameters. EFFECT: enhanced quality of ceramic material. 2 tbl
