Beschreibungen/Notizen

• We have studied by in situ neutron diffraction the crystallization process of the Bi2212 phase sheathed in Ag-tapes. During the first heating of the tape, there is a grain reorientation of the silver tape, in such a way that the (1 1 1) planes are orientated perpendicularly to the tape. After melting of the 2212 phase at 880°C and the peritectic decomposition, the phase is quickly reformed during the cooling between 880°C and 750°C. During the long annealing process at 890°C, we have observed a small change in the c parameter, that can be attributed to an oxidation process.
