Description
The effect of the Si-doping on the superconducting properties and microstructure of Bi-Pb-Sr-Ca-Cu-O bulk materials has been investigated. It has been found that the superconducting transition temperature showed no considerable change in Si-doped Bi-Pb-Sr-Ca-Cu-O materials, while the critical current density was found to be significantly improved. The microstructures of both Si-doped and Si-free materials were characterized by bar-shape grains and indeterminate shape grains, but the bar-shape grains in the Si-doped materials were much more and longer than those in the Si-free materials. The microstructural change can be considered to be one of the possible reasons to lead to the improvment of the critical current density in the Si-doped materials
