Abstract: Using the "sessile drop" method the angle of contact between graphite and the cryolite-based melt was investigated. The influence of the additions of LiF, CaF₂, MgF₂ and of dissolved aluminium on wetting of graphite by the melt was studied. It was found that the dissolved aluminium remarkably changes properties of the graphite-cryolite melt interphase while the additions of LiF, CaF₂, and MgF₂ have only mild influence on this parameter.
