A Simple Method of Fabricating Preferentially Oriented YBa2Cu3O7-x Film on Silver Substrates
Abstract
Porous YBa2Cu3O7-x film stuck to a flexible silver substrate was easily fabricated by sintering a doctor-blade-cast green sheet of YBa2Cu3O7-x placed on the silver substrate. Furthermore, preferentially oriented dense YBa2Cu3O7-x film was also fabricated by adopting a copper plated silver substrate and then sintered below the melting temperature of silver. A possible mechanism for the appearance of the preferentially oriented dense YBa2Cu3O7-x is discussed based on the liquid-phase sintering in the YBa2Cu3O7-x-CuO-Ag system.
