Abstract
The porosity remaining in Bi2212/Ag monocore tapes after melt processing is shown to be a function of the conductor geometry. The effect of other processing variables on the final microstructure was studied. It was found that increasing the length of the soak time, t m, at the maximum processing temperature increases the size of second-phase particles and the fraction of 2201 intergrowth layers within the 2212 grains.
