Dissolution of alumina in mold fluxes
Abstract
The solubility and rate of dissolution of alumina in a range of mold fluxes in the CaO-Al2O3-SiO2-Na2O-CaF2 system have been measured at 1530 °C using the rotating finger method. The solubilities were approximately 38 pct for all fluxes studied. The kinetics of dissolution were correlated with the Levich-Chochran equation for a rotating disc and used to determine the effective diffusivity of alumina. The effective diffusivity was inversely …
