Abstract A major phase in high Tc Y-Ba-Cu oxide with zero resistance at 91K and high volume fraction of diamagnetic superconductive phase has been identified by electron diffraction. It appears to be an orthorhombic twinned structure with a=3.89Å, b=3.82Å and c=11.7lÅ. Some defects were observed by TEM.
