We have studied the effects of the incorporation of polyvinyl acetate (PVA) aqueous solution on the formability of the precursor Y-Ba-Cu-O samples with the aim of improving the mechanical properties of large bulk RE-Ba-Cu-O superconductors that are susceptible to cracking. We found that the green compacts of YBa2Cu3Oy and Y 2BaCuO5 powders added with PVA liquid binder exhibited good mechanical properties and could be mechanically machined without defects. We could successfully drill 17 holes of 1 mm diameter into the green compact. The drilled samples were subjected to melt-processing and oxygen annealing, and further characterized with microstructural observations and magnetization measurements. The results showed that liquid binder addition was very effective in reducing cracks for large melt-processed Y-Ba-Cu-O superconductors.
