摘要：

The microstructures of high-T//c superconductor GdBa//2Cu//3O//7// minus // delta prepared under various sintering conditions were observed by using a scanning electron microscope and an electron microprobe analyzer. The second phase was found on the grain boundaries of the samples sintered at temperatures higher than 970 degree C. The phase was confirmed to consist of more Ba and less Gd in comparison with the composition of the grain.
