A study of masses based on chemically synthesized materials in the system MgO-Cr2O3

Additions in the form of TiO2 or ZrO2 are recommended in order to obtain effective sintering of the chemically synthesized composite MgO + MgCr2O4, obtained from the thermal decomposition of magnesium chromate. The articles prepared in accordance with the new process based on dense-sintered clinker have excellent physicochemical properties. The experimental tap hole blocks made using the clinker process showed 1.5 times greater resistance than that of fused periclase blocks when tested at the Nizhnetagilsk Metallurgical Combine.
