ABSTRACT:
A ceramic superconductive material (1) including a compound containing oxygen and at least two types of metal elements and having layer structure is molten in a vessel (2), at least an inner surface (3) of which is formed of a solid solution alloy having a base of gold or silver. Preferably the alloy is prepared from Au--5 to 40 wt. % Pd or Ag--5 to 40 wt. % Pd.
