Changes in the phase composition of the MgO – Al2O3 – SiO2 system in the subsolidus region are studied by the thermogravimetric method. Specific features of the DTA curves are correlated with periodic changes in the concentration of phases involved in chemical reversible solid-phase reactions. Critical kinetic effects associated with conjugated solid-phase reactions in the MgO – Al2O3 – SiO2 system are discussed in terms of graph theory. The phase composition of materials with a dissipative structure is shown to form by a self-organization mechanism.
