Abstract
The existence of a special class of Mn – i Xn – i superstructures (n – integer constant, i – rational variable) formed as a result of incomplete second order equilibrium order–order phase transitions in compounds with atomic vacancy ordering has been theoretically substantiated. The superstructure M5 – iX5 – i (i = 1; 11/18; 14/18) of the high-temperature ordered titanium monoxide phase β-TiO has been described in detail as an example.
