Abstract

A “grain coating” technique was developed to improve the intergranular links in YBa₂Cu₃O_x ceramics. Thin layers of additives such as Ag, SnO₂, Bi_2O ₃ were introduced into the grain boundaries by vacuum evaporation. Notable J_c increments due to grain coating were observed. TEM investigation revealed that dislocations accompanied by stacking faults existed in these samples.
