摘要：
Equilibrium solubility of alumina in the cryolite melts containing 26 mass % excess AIF(3) and additions of LiF (up to 7 mass %), CaF2 (3.5 mass %), and/or MgF2 (up to 10 mass %) was determined. Rate of dissolution of alumina in the melts of given composition was investigated. It was found that the experimental data can be described by a hyperbolic relationship with two adjustable parameters. One parameter corresponds to the equilibrium solubility of alumina in the melts. The other parameter characterizes the used alumina, temperature, and composition of the melt.
