Importance of Avrami Index in the processing of bismuth based high temperature superconductors

摘要: Abstract It is well known that processing of Bismuth based high T c perovskites difficult and often results in only multiphase systems. Innumerous reports on parameters like annealing temperature, time, selection right combination elements addition dopants Pb are available since a long time still the synthesis single phase High not an easy task contrast to Yitrium cuprates. Here we report for first how knowledge Avrami Index (dimensionality crystal growth) provides critical insight selecting mixture Lead doped cuprates forming highly compound through glassy precursor route.
