Based on the results for the time dependence of F, Ca, Si and Al amount dissolved from hot metal pretreatment slags, the behavior of fluorine dissolution has been examined. It was found that the amount of fluorine dissolved from hot metal pretreatment slag depends on CaO/SiO2 mass ratio and fluorine content in slag. This trend is obvious in the case of synthetic slags. Fluorine ion in solution is incorporated into CaO-SiO2-H2O and CaO-SiO2-Al2O3-H2O gels during the formation of these gels. Therefore, it was found difficult to estimate the amount of fluorine in solution from the amount of F-containing mineral phases and slag compositions.
