Abstract

Crystallochemical data for the Ho2SrAl2O7 oxide at 100, 293, and 673 K were obtained by full-profile X-ray analysis. Analysis of the thermal expansion anisotropy showed that increased temperature gives rise to equalization of metal-oxygen bond lengths in all oxygen polyhedra at the expense of lengthening of some bonds and virtual invariability of others.
