Abstract
The effect of cooling conditions on microstructure and electromagnetic properties of Bi2212/Ag monocore tapes and multifilamentary round wires was studied. We found that using isothermal solidification at temperatures 5–8 °C below the peritectic decomposition temperature of the 2212 phase it is possible to consume almost all second-phase particles present in the melt and reduce the density of 2201 intergrowths below 1%, but this occurred at the expense of forming larger amount of 2201 as a separate phase. Different optimum cooling rates were found for tape and wire samples.
