Abstract

The lattice parameters of HgxBa2O4+δ were determined by X-ray powder diffraction as a function of temperature from 10 to 310 K. The fitting of the parameters yielded the thermal expansion coefficients of the superconducting oxide and demonstrated the anisotropy characteristics of the polycrystalline material. The effect of the irreversible loss of Hg on the lattice parameters is reported.
