    Material Specification for Bi:2212; [Bi-Sr-Ca-Cu-O] Process: Solid State Reaction
    Notes: "The Bi-based 2212-phase single crystals were grown by cooling nonstoichimetric melts in Al2O3 crucibles from 1000 °C at the rate 5-10 °C/h. The composition of melts was Bi4Sr3Ca(R)3Cu4... The amount of R varied from 0 to 50 mol% relative to Ca. If Pb was present, its amount was 10 mol% relative to BiO1.5. The temperature regimes differed from one another with the rates of heating and cooling to produce samples with identical structures for the different compositions... For determination of sample compositions, an x-ray spectral microanalyzer device of the CAMECA scanning electron microscope was used. The accuracy of the element content C determination was better than 5%. The sample formulas were calculated relative to the Cu content which was taken equal to 2."
