摘要
A non-weak link joining technique has been developed for YBCO pseudo-crystals fabricated by seeded peritectic solidification based on the formation of a liquid phase which segregates from the platelet boundaries at temperatures above approximate to 920 degrees C, Electrical and magnetic measurements on these boundaries suggest that their irreversibility field can be as high as 7 T at 77 Ii in fully oxygenated pseudo-crystals joined along their crystallographic ab-planes which is comparable to the irreversibility behaviour of the adjacent YBCO grains.
