Subsolidus Structure of the MgO – Al2O3 – FeO – TiO2 system

The subsolidus structure of the four-component system MgO – Al2O3 – FeO – TiO2 was studied in six temperature ranges. Geometric-topological characteristics of the phases of the system under study have been determined, topological graphs of the relationship of elementary tetrahedrons have been constructed, their volumes, degrees of asymmetry for all temperature ranges have been found.

PECULIARITIES OF THE PHASE COMPOSITION OF ASH AND SLAG WASTE FROM THE THERMAL POWER STATION

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.
