Formation of material properties

In the production of refractories, clinker technology is used, which results in the formation of various spinels of the type MgCr2O4, MgAl2O4and MgFe2O4. An important role in the production of refractories belongs to two spinels - MgCr2O4, MgAl2O4. The main disadvantage is poor sintering. This property degrades the strength and compaction of refractory products. Magnesite spinels and their solid solutions are among the main phases of refractories, and phase transformations in refractories during heating strongly affect their properties. The result of the calculations using a software package that reveals the phase and component composition of the thermodynamic system is that spinels change their chemical activity at a temperature of about 800 °C. The results of dilatometric measurements help to explain the anomalous behavior of spinels, which simplifies the analysis of the influence of the third component.
