Abstract

The melting and recrystallization behaviors of (Bi, Pb)-2223 core in the Ag-sheathed tape have been investigated via static melting experiment under different conditions. The feasibility of the (Bi, Pb)-2223 reformation directly from the melt has been investigated. It is shown that a partial melting of high-Tc core at some temperature in an appreciate range, which bring a 2212-like melt and alkaline earth cuprates (AEC), especially 14:24-AEC and 2:1-AEC, is very important for establishing the equilibrium transformation between (Bi, Pb)-2223 and the melt.
