Abstract: Samples were prepared from oxides in the atomic ratio of Ba:Y:Cu=1:1:1 by solid state reaction.The appearnce of the products ranges from dark to green and a few of them are not uniform in color.They are stable in air and disintegretes into powder when immersed in water. They show Meissner effect; R-T curves of them show zero-resistence temperature at 85.9-88.4K. X-ray diffraction pattern shows that it is a multiphase system and one of the main phase is orthogonal with cell constants of a=3.86, b=3.84, c=11.62Å. SEM photos show that there are two species in micromorphology With composition of Ba: Y:Cu=1:2:1 and 3:2:5 respectively, through EDS measurements.
