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.

Methods of obtaining of magnesium-aluminate spinelpowders. Review

The main methods of synthesis of magnesium-aluminate spinel powder their features and advantages were analyzed. The character of the physicochemical interaction of components in theMgO–Al2O3 system physical and crystallographic characteristics and structural parameters of thecrystalline lattice of magnesium-aluminate spinel wereresearched. The synthesis conditions arepresented and qualitative comparison of the possibilities of synthesis methods in terms of theproperties of spinel powders are made.
