Electrical current suppression mechanism in Bi-2212 bulk obtained by partial melting processing

Partial melting technique consists of peritectic melting and solidification of Bi-2212 phase. This technique has been applied in two temperature ranges of the Ca poor part of the Bi 2.20Sr 3− y Ca y Cu 2O 8+ Δ system phase diagram, both involving multi-phase regions, with the aim of preparing bulk a...

Zusammenfassung:Partial melting technique consists of peritectic melting and solidification of Bi-2212 phase. This technique has been applied in two temperature ranges of the Ca poor part of the Bi 2.20Sr 3− y Ca y Cu 2O 8+ Δ system phase diagram, both involving multi-phase regions, with the aim of preparing bulk and dense Bi-2212 phase. Microstructural and intrinsic physical parameters which could act as potential suppression mechanisms of the electric transport properties of bulk Bi-2212 have been discussed.
