Abstract

Based on the experimental data on the density, the molecular dynamics simulation of multicomponent oxidefluoride melts was first carried out in the ionic bond model approximation: SiO2-CaO-Al2O3-MgO-CaF2- Na2O-K2O-FeO. The results are discussed and compared with the experimental and calculated data. An increased diffusion mobility of fluorine ions as well as ions of alkali metals in comparison with other elements has been revealed. It is shown that the computer model allows obtaining adequate information about the structure of the melt of a certain chemical composition, as well as a fairly realistic picture of the atomic structure of the slag melt, which, according to the main parameters, agrees well with the data of the diffraction experiment.
