Abstract

The heat treatment of (Bi,Pb)2223 tapes in a furnace with a temperature gradient allows the study of many heat treatment temperatures at the same time. 20 cm lengths of tape were given a typical first heat treatment of a period of 40 hours in a ~1°C/cm temperature gradient under either 7.5% partial pressure O2, or air. The maximum amount of (Bi,Pb)2223 occurred in a temperature window, (⩽2% change in the phase composition) of about 7°C under 7.5% partial pressure and 2°C under air. The relationship between the phase composition and the transport current, Ic, for both atmospheres is investigated
