The phase composition of ash and slag from thermal power stations (TPS) were studied. It was established that ashes from thermal power stations are not homogeneous glass in the structure and are characterized by the presence of a significant number of mullite and hercynite crystallization centers. The phase composition and structure of ash slag were investigated by XRF and SAR methods. It was established that the processes of crystallization of iron-aluminosilicate slag finishes at the stage of nucleation of crystals whose further growth becomes impossible because of the sharp increase of viscosity during cooling.
