| dc.description | The potential for the use of microwave radiation as an alternative energy source for the melt texturing of bulk, ceramic high- YBCO superconductors has been investigated with a view to taking advantage of the opportunities presented by this novel heating technique. T-shaped samples of 83% dense, sintered YBCO were melt processed, both conventionally and using microwave energy, whilst suspended within two different casketing arrangements. Samples consisting of densely packed, long grains all aligned with the axis of the sample could be obtained under the best conditions. In addition, completely uniform and full oxygen contents (x = 7 in ) could be obtained throughout all the microwave-processed samples when the melt processing temperature was kept in the range . However, on the negative side, this appeared to limit the maximum density to 94% of theoretical unless a slight drop in x to 6.98 could be tolerated. The higher processing temperatures, which yielded the best microstructures, also resulted in 5-8% of the 211 phase being present. |
