Description
The dependences of intermediate phase concentrations on the heating temperatures of initial mixtures for two variants of high Tc Y Ba2 Cu3 O7 (123) synthesis were studied by means of thermogravimetry (DTA, DTG) and X-ray diffraction (RDA). As expected, Cu2 O lowers the temperature of maximum (123) content (∼ 590o C). The reciprocal relation between (123) and (143) phase concentrations have been observed for both syntheses of (123) superconducting phase with Tc > 80 K. RDA data show on the perovskite-like structure of (143) phase with ABO3 (Ba4 [Y Cu3] Ox) composition (a = 4.04 AA). (Author)
