Bulk Y2BaCuO5has been found to have a higher stiffness but a lower thermal expansion than YBa2Cu3Ox. Y2BaCuO5exhibits semiconducting behavior at room temperature. Composite tapes consisting of layers of Y2BaCuO5and YBa2Cu3Oxcracked upon sintering because of large differences in shrinkage rate. Addition of 15 volume % Ag to the YBa2Cu3Oxstrengthened the material and prevented cracking.
