Research interests
- Equilibrium-state in complex systems: Iterative equilibrium constant method (IECM)
- Steady-state (virtual equilibrium) in a closed reactor subjected to temperature-gradient
- Gas-solid reaction rates: mass-transfer effects and determining intrinsic kinetics. Liquid-gas reaction kinetics at steelmaking temperatures and effects of surface-active elements (oxygen; sulfur) on nitrogen absorption and desorption in ferrous melts
- Chemical vapor deposition of optoelectronic materials
- Sulfide-smelting: suppression of polluting sulfur-oxide emissions
- Carbothermic chlorination of alumina and rutile minerals
- Catalyzed gasification of carbon; flue-gas desulfurization; acid-mine-drainage
- Midrex direct-reduction ironmaking process
- Stage-wise models for Corex smelter-gasifier process and iron Blast-furnace process. Phase-equilibria and construction of phase-boundaries in the W-Si-H-Cl-Ar system
