Abstract
A new method for joining superconductors by microwave heating has been developed. Bars of microwave-joined, Y-based ceramic superconductors show good mechanical integrity. After they are postannealed, the sampl es show superconducting transition at around 89.7 K. Meanwhile, the ba ckscattered electron images of the joined region after postannealing i n air at 960-degrees-C for 15 h show a higher density in the joined re gion, which has larger pores that may be caused by an accumulation of small pores during post-heat-treatment.
