摘要：

X-ray diffraction data are obtained on polycrystalline samples of zircon (ZrSiO4) and almandine (Fe3Al2Si3O12) from 100 to 300 K using x-ray diffraction beam line at Elettra synchrotron source. The observed thermal expansions in zircon and almandine, which differ by a factor of 2-3, are found to be in good agreement with the predictions from our lattice-dynamical calculations. The calculations also enabled a microscopic interpretation of the available experimental data.
