A “grain coating” technique was developed to improve the intergranular links in YBa2Cu3Ox ceramics. Thin layers of additives such as Ag, SnO2, Bi2O 3 were introduced into the grain boundaries by vacuum evaporation. Notable Jc increments due to grain coating were observed. TEM investigation revealed that dislocations accompanied by stacking faults existed in these samples.
