| Research Abstract |
Dynamics studies on volatilization of lead compounds from SiO_2-Al_2O_3-CaO molten slag, accompanied by chlorination and sulfidation reactions of PbO with Cl and S compounds, were conducted. Results showed that the volatilization of lead compounds of lower boiling temperatures which were produced by the reaction of PbO with coexisting inorganic chlorides or HCl and H_2S gas was promoted. Results also showed that the rates of volatilization of lead compounds were higher from molten slag of lower viscosity with higher CaO content.
