Materials and Properties

Bi:2212; [Bi-Sr-Ca(Gd)-Cu-O]
Material Specification for Bi:2212; [Bi-Sr-Ca(Gd)-Cu-O] Process: Solid State Reaction
Notes: "Samples... were prepared by solid-state reaction of appropriate quantities of well-mixed metal oxides and carbonates which were reacted at 850 °C for 72 h. The reacted materials were pulverized and cold pressed into pellets which were sintered and annealed in air or oxygen in the temperature range 860-910 °C. One set of air-annealed samples is further annealed in nitrogen at 650 °C. A second set of samples is quenched in liquid nitrogen."
