Abstract
The kinetics of dissolution of SiO2 into liquid iron has been investigated by a method of rapid rise of the temperature of the melt in silica crucible from 1550° to 1600°, or 1635°.
The oxygen increase of liquid iron is rate-controlled solely by interfacial reaction, until the equilibrium at these temperatures is reached.The following reaction in which the oxygen adsorbed at the crucible-melt interface takes part as a reactant explained well the experimental results.
SiO2+O(ads)=Si+2O+O(ads)
It is impossible to discuss the phenomena of the Si-deoxidation under the assumption that the local equilibrium is kept at the interface where the reaction proceeds.
The oxygen adsorption isotherm for the interface is-estimated.
