Some Novel Studies of Thermodynamics, Kinetics and Transport Phenomena in Slags

Abstract

The following paper revolves around the research work conducted in collaboration during Profes sor Iwase's brief visits to the Materials Process Science Division at Royal Institute of Technology, Stockholm. The paper focuses on the thermodynamic aspects of CaOFeO-SiO 2 and CaO-FeO-SiO 2 -MnO slag oxidation in air and sulfur transport through CaO-Al 2 O 3 -SiO 2 slag. Ther modynamics of slag oxidation in air opens potential new areas in terms of focus on effective recovery of iron oxide from slag. The slag transport studies are of fundamental nature and focuses on a novel technique to calculate the diffusion of species through slag by analyzing its corre sponding concentration in the metal phase.
