Abstract

Abstract:

Study on the kinetics of oxidation of Ti-enriched slag (CaO-SiO_2-Al_2O_3-MgO-TiO_x-FeO_y system)was carried out by E. M. F. method and chemical analysis. The diffusion rate constants of oxygen within the molten slag were obtained which are 0.66×10-5 m•s-1 and 1.98×10-5 m• s-1 respectively. The experimental work showed that E. M. F. is a quick and convenient method.

Key words: Slag, Kinetics, Solid electrolyte, Diffusion, TiO2
