Abstract
The experimental part of this thesis, Powder Processing of Bi-Pb-Sr-Ca-Cu-0 Superconductors, contains of four main parts: a) Sample production techniques and their comparison (in terms of stoichiometry, phase composition, homogeneity, particle size, reactivity), characterisation of Bi-Pb-Sr-Ca-Cu-0 precursor powders; and the influence of the precursor powder properties, mainly in terms of particle size, on Jc of the Agsheathed tapes; b) methods of particle size reduction and particle size distribution measurements of the Bi-based superconducting precursor powder; c) investigation of the development of the high-temperature (Bi-2223) phase and its formation kinetics; d) effect of grain boundaries on electrical properties of the bulk Bi-Sr-Ca-Cu-0 system in terms of Tc and Jc values; and the effect of plastic deformation on grain boundaries and recrystallisation.
