Phase composition and properties of superconducting ceramics based on Bi1.7Pb0.3Sr2Ca2Cu3O y precursors fabricated by melt quenching in a solar furnace

cited By 1International audienceProduction of superconducting ceramics based on precursors with rated composition Bi1.7Pb0.3Sr2Ca2Cu 3O y is studied. The precursors are synthesized in a solar furnace by melt rapid quenching. The phase composition of the samples is examined by microstructural and X-ray analyses. The temperature dependences of the resistance and magnetic susceptibility are measured. The influence of the composition and crystal structure of the substrate on texturing in the Bi-Sr-Ca-Cu-O system is studied. It is found that the type of quenching plays a significant role, while the type of substrate is of minor significance. © 2009 Pleiades Publishing, Ltd
