    Abstract

    A low-temperature X-ray powder diffractometer has been developed and applied to the measurement of lattice constants of Bi2Sr2CaCu2Ox superconductor at 80 K, only 3 K higher than the critical temperature. The relationship between the lattice constants and electrical resistivity was studied. The Bi2Sr2CaCu2Ox sample was prepared by solid-state reaction and sintered by a hot-press system at 750°C. Lattice constants of the Bi2Sr2CaCu2Cx were measured at 293 to 80 K. The electrical resistivity of the sample, measured by the standard four-probe method, reached 0 Ω cm at 77 K. The resistivity decreased rapidly along with rapid shrinkage of the c-axial length.
