Influence of TiO2 on viscosity, phase composition and structure of chromium-containing high-titanium blast furnace slag

Journal of Materials Research and Technology, 2021
The viscous flow of CaO–SiO2–Al2O3–MgO–TiO2–Cr2O3 slag (CaO/SiO2 = 1.1, Cr2O3 = 0.5 mass%) were investigated to promote understanding of the effect of TiO2 addition on the viscous behavior of chromium-containing vanadium-titanium blast furnace slag.

Impact of MgO Additions on the Oxidation Resistance and Compression Behavior of Vanadium Alloys

Advanced Engineering Materials, EarlyView.
An increase in oxidation resistance at 600 °C is achieved for alloys containing more than 2.5 wt.% MgO. It has been established that, along with V2O5, MgO6V2, and Mg2O7V2 are formed, which are presumed to enhance oxidative stability. Furthermore, the possible transformation of Mg‐vanadates through reaction with CO2, which presumably occurs in this ...
