抜粋

We have studied the formation of pores in melt-processed RE-Ba-Cu-O. The pores were partly formed due to the oxygen bubbles generated during the peritectic decomposition of RE123 via RE123 → RE211 + liquid + O2. When the sample was heated to the temperature high above the peritectic decomposition temperature, a large amount of oxygen gas was generated from the sample. The inert gas entrapment during melting also caused pore formation. The control of the composition, atmosphere and heating conditions was effective in reducing the amount of pores.
