We have characterized grain boundaries (GBs) in YBCO bulk superconductors grown by the multi-seeded melt-growth (MSMG) process. Microstructural analyses revealed that GBs formed in the c-growth sectors were free from residual liquid phase. Strongly coupled GBs could be formed when the crystal growth directions of two grains were along 〈110〉 directions. We found that GBs in the c-growth sector with 〈110〉 growth direction exhibited superconducting properties comparable to the matrix.
