Abstract
For synthesis of superconducting oxide composition YBa2Cu307-x is used a plasma process of decomposing a mixed nitric solution of Yttrium, Barium, Copper. There are considered principles of the process applicable to desintegrating the solution in to the stream of air low-temperature plasma. The apparatus used for synthesis of YBa2Cu307-x is described. Synthesized powders have high-temperature superconductivity (Tc=90-95K).
