Processing and characterization of microwave and conventionally sintered bulk YBCO high-{Tc} superconductors
- Univ. of Nottingham (United Kingdom)
The use of microwave energy for the sintering and annealing of high-{Tc} YBCO superconductors has been investigated with a view to taking advantage of the opportunities presented by this heating technique. It has been found to offer the possibility of sintering from the inside out due to the nature of the temperature profile developed and as a result bulk YBCO bodies measuring 35 mm in diameter by 5 mm thick have been produced with completely uniform and high oxygen content (x = 7 in YBa{sub 2}Cu{sub 3}O{sub x}) and densities of {approx}98% of theoretical. These properties were achieved using processing times approximately one sixth of those required conventionally. A model for the microwave heating process is proposed.
