Abstract The relationship between the transport J c and the microstructure of the bulk YBa2Cu3O7−03B4; samples prepared in various sintering conditions has been studied. The results show that the oxygen atmosphere during sintering and cooling not only influence the crystal structure of the grains but also the grain sizes and the nature of the grain boundaries. The pellet forming pressure affects the orientation of the grains. The width of the grain boundaries is the most important factor in determining the values of transport J c.
