Dataset for: Viscosity and Structure Evolution of Blast Furnace Slag from Limonitic Laterite Nickel Ore with Varying CaO/SiO2 Ratios: Experiments and Molecular Dynamics Simulationsn

This dataset supports the research article entitled “Viscosity and Structure Evolution of Blast Furnace Slag from Limonitic Laterite Nickel Ore with Varying CaO/SiO₂ Ratios: Experiments and Molecular Dynamics Simulations.” The dataset contains experimental viscosity and molecular dynamics simulation data for the CaO–SiO2–MgO–28.5 wt% Al2O3–6.0 wt% Cr2O3 slag system with CaO/SiO₂ mass ratios of 0.80, 0.85, 0.90, 0.95, and 1.00. The experimental data include viscosity–temperature measurements and apparent activation energies.The structural datasets include radial distribution functions, coordination numbers, bond-angle distributions, Qⁿ distributions of Si- and Al-centered tetrahedra, oxygen-species distributions, and charge-compensation statistics.These data are provided to facilitate independent verification, reproduction of the calculations, and further investigation of the relationship between the CaO/SiO2 ratio, melt structure, and viscosity of high-Al2O3–Cr2O3 blast furnace slags.
