摘要：

Method of determining temperature dependence of lattice parameters and crystal cell volume of ferroelastics in analytical form at 4 / m F 2 / m structural phase transition has been suggested on the basis of conservation condition of paraelastic phase macrosymmetry in a polydomain crystal. The analysis of functions for the sample of BiVO4 was made. Temperature dependence of the spontaneous strain components and crystallographic axes spontaneous rotation are determined for the crystal.
