Title (EN) OXIDE SUPERCONDUCTOR
(FR) SUPRACONDUCTEUR A BASE D'OXYDE
Abstract: front page image
(EN)An oxide superconductor of the molecular formula: MBa2-xCaxCu3O7-x, wherein M represents La, etc., and 0 < x « 1.8 except the case where x = 1.0. Other examples of the superconductor include those prepared by adding at least one member selected from the group consisting of Ca2CuO3, CaCu2O3 and CaO in a total amount of 0.01 to 60 % by weight to 1 mol of MBa2Cu3O7-x, 1 mol of at least one member selected from the group consisting of Tl2Ca2Ba2Cu3Oy, Tl1Ca2Ba2Cu3Oy, (Tl, Pb)1(Sr, Ca)4Cu3Oy, and (Tl, Pb)1(Sr, Ca)3Cu2Oy, or 1 mol of (Bi, Pb)2Sr2Ca2Cu3Oy or/and Bi2Sr2Ca2Cu3Oy.
(FR)Supraconducteur à base d'oxyde selon la formule moléculaire MBa2-xCaxCu3O7-x, où M représente La, etc., et 0 < x « 1,8 sauf lorsque x = 1,0. Des variantes de ce supraconducteur comprennent des composés obtenus par l'addition d'un élément au moins sélectionné dans le groupe composé de Ca2CuO3, CaCu2O3 et CaO en une quantité totale allant de 0,01 à 60 % en poids à 1 mol de MBa2Cu3O7-x, 1 mol d'un élément au moins sélectionné dans le groupe composé de Tl2Ca2Ba2Cu3Oy, Tl1Ca2Ba2Cu3Oy, (Tl, Pb)1(Sr, Ca)4Cu3Oy, et (Tl, Pb)1(Sr, Ca)3Cu2Oy, ou 1 mol de (Bi, Pb)2Sr2Ca2Cu3Oy et/ou Bi2Sr2Ca2Cu3Oy.
