Di. Grigorashev et al., ON THE FORMATION AND PROPERTIES OF BI-2212 PHASE WITH DIFFERENT CATION COMPOSITION, Physica. C, Superconductivity, 282, 1997, pp. 867-868
Formation of 2212 phase from mixtures with different cation compositio
n was studied. It was found an extremely high rate of target product s
ynthesis from Cu-free precursor mixed with copper oxide. Both the supe
rconducting properties and real structure of synthesised materials dep
end from cation composition of starting mixture.
