Abstract: | A general concept of the symmetry transformation of a material during its thermal expansion and final polymorphic transition
is proposed based on numerous experimental data. Within this concept, the atomic nature of the transformation of the crystal
structure with a change in temperature is considered. Particular attention is paid to the thermal expansion of materials,
along with the well-known tendency of a thermally induced increase in the crystal symmetry, which is generally considered
to be the directionality of material transformation during polymorphic transitions. |
