Description
Aimed to design the technology of YBCO superconducting crystal growth the investigations were carried out on phase formation in CuO-CuBaO2 system. A new method of YBa2Cu3Ox single crystal growth was proposed. Crystals were grown from CuyBaOz solution-melt at 900 deg C under oxygen pressure varying of 0.02 to 0.21 atm. for 50-100 h. The use of low pressure allowed one to decrease essentially the temperature of initial treatment that in turn made it possible to reduce the amount of impurities from crucible material. According to technology described superconducting single crystals were obtained as large as 5x5x0.1 mm with transition temperature Ts equal to 93 K
