Professor In-Ho Jung's research lab specializes in computational thermodynamics and materials modeling, focusing on the thermodynamic behavior of complex oxide and metal systems relevant to high-temperature metallurgical processes. The lab develops advanced thermodynamic databases and models—such as the Modified Quasichemical Model—for molten slags, steel, inclusions, and refractories, enabling accurate prediction of phase equilibria in multi-component systems. Their work supports industrial applications in steelmaking, particularly in optimizing deoxidation processes and understanding inclusion formation. The lab emphasizes the integration of experimental data with computational tools to enable predictive simulations under realistic processing conditions.

Computerized thermodynamic databases for solid and liquid steel, slags and solid oxide solutions, for large numbers of components, have been developed over the last two decades by critical evaluation/optimization of all available phase equilibrium and thermodynamic data. The databases contain parameters of models specifically developed for molten slags; liquid and solid steel; and solid oxide solutions such as spinels. With user friendly software, which accesses these databases, complex equilibr
All available thermodynamic and phase diagram data have been critically evaluated and optimized for the liquid slag phase and for all solid phases at 1 bar pressure from 298 K to above the liquidus temperatures for the systems Al2O3–TiO2, Al2O3–Ti2O3, and Al2O3–Ti2O3–TiO2, and a database of model parameters has been prepared. The Modified Quasichemical Model was employed for the molten oxide phase. The thermodynamic modeling predicts the existence of a liquid oxide Al2O3–Ti2O3–TiO2 phase at seco
