X-ray diffraction and EDS analysis of Y1Ba2Cu3O9−y superconducting compound

On the measurement of microwave absorption of bulk YBaCuO superconductors in X-band (8–12 GHz)

“…After thorough mixing the powder was calcinated at 950°C for 24 h. After granulation, pellets of desired dimension (0"9" × 0.4") were formed and sintered at 950°C for about 10 h in oxygen ambient followed by slow cooling (2°C/min). Critical temperature of 91 K was observed in these samples (Singh et al 1988).…”
