X-ray diffraction study of anisotropic thermal expansion in ZrMo2O8

Abstract

Temperature-dependent X-ray diffraction measurements are reported for ZrMo2O8in the trigonal phase from 80 to 925 K. The measurements reveal highly anisotropic thermal expansion coefficients with average values of −3.9 × 10−6and 52 × 10−6 K−1for theaandccell parameters, respectively.
