The effect of heat treatment on the critical current density, jc was studied for monofilament tape samples without intermediate rolling. Bi1.6Pb0.4Sr2Ca2Cu3O7+d polycrystalline ceramic powder was prepared by co-precipitation technique. The tape samples were prepared using standard powder-in-tube method and were sintered at 850˚C at different sintering time. XRD result shows the peaks (00l) that belong to the 2223 phase which appear with the increase in sintering time. The electrical transport and magnetic properties of the tapes werewas characterized from 60 K to 77 K in zero magnetic fields and in magnetic field up to 0.6 T at 77 K. The transport critical current density, jc for the tape sintered for 24 hour is 2400 A/cm-2 and is 6000 A/cm-2 for tape sintered for 100 hour. This showed that нннннннннн jc increases with the increasing of the sintering time.
