摘要：

The kinetics of the synthesis of YBa2CU3O7-y (YBCO) was studied in situ on an X-ray diffractometer using the time vs temperature dependences of the concentration of the phase. The highest rate of YBCO synthesis was observed at 750-780degreesC. The effective activation energy was minimal at 700degreesC, E-a = 20-30 kJ/mole. The structural nonhomogeneity parameters and the dimensions of coherent scattering regions were determined for the YBCO product.
