Freestanding thick films of YBa2Cu3O6.9 by screenprinting techniques

Thick (20–300 μm) freestanding polycrystalline films of ceramic YBa 2 Cu 3 O 6.9 have been obtained by resintering YBa 2 Cu 3 O 6.9 powder in air after screen printing onto fused silica substrates. An interfacial reaction occurs between the powder and the silica substrate which efficiently detaches the resintered film upon cooling. The magnetization and transport properties of these films are comparable to those for high quality bulk ceramic samples.
