Abstract

A structural identification of the superconducting phase in the Bi-Sr-Cu-O system has been carried out by X-ray and electron diffraction. A lamellar oxide structure expressed by the formula Bi2(Bi, Sr)2CuOx with the orthorhombic a = 0.537 nm, b ≃ 5 · 0.537 nm and c = 2.463 nm (pseudo-tetragonal subcell a = 0.5369 (l) nm and c = 2.4627 (5) nm) is found to be responsible for the superconductive property. The structural model of this compound is compared with the Aurivillius phases.
