A facile strategy for the design of porous supports was obtained by modifying sol-gel method followed wet impregnation technique. In this respect, herein, acidity γ-Al2O3 phase modulated adding basic MgO, La2O3 or ZnO promoters to form binary supported catalysts. The Ni and Co dispersion on associated with their tunable morphologies resulted in highly alumina-based physicochemical properties so...

Analyses of coarse-grained refractory inclusions typically do not have the solar CaO/Al2O3 ratio, probably reflecting nonrepresentative sampling of them in the laboratory. Many previous studies, especially those done by instrumental neutron activation analysis (INAA), were based on very small amounts of material removed from those restricted portions of inclusions that happened to be exposed on...

Al2O3 substrate is widely used as a lining refractory material throughout the blast furnace (BF) process. Accordingly, erosion of by molten slag has negative influence on running cost and smooth operation BFs. The effect behavior BF primary containing FeO-CaO-SiO2-MgO-Al2O3 was fundamentally investigated using high-temperature contact angle method FactSage thermodynamic software based compositi...

Using a novel experimental procedure in the field of ceramics/materials science that is based on the precise microanalysis (scanning electron microscopy, coupled with wavelength-dispersive spectroscopy) of the phases that are present in equilibrated specimens, the solid-state compatibility relations in the subsystem MgAl2O4–CaAl4O7–CaO– MgO and the melting relationships in the subsystems MgAl2O...
