| Summary: | Заглавие с экрана The possibility of plasma dynamic synthesis of yttrium-barium cuprates for high-temperature superconductivity with using coaxial magnetoplasma accelerator is shown. The synthesis process is no longer than 500 ms. The use of yttrium nitrite and barium hydroxide precursors together with copper obtained due to electro erosion during the plasma flow movement allows to synthesize yttrium-barium cuprates. To exclude impurities of the final product the annealing is carried out. The obtained after annealing powder is used to produce the ceramics by magnetic-pulse pressing and sintering. According to X-ray diffractometry analysis the produced ceramics has a structure similar to the reference of yttrium-barium cuprates. The possibility of obtaining yttrium-barium cuprates powder and producing the ceramics based on this powder is shown. Режим доступа: по договору с организацией-держателем ресурса |
