Abstract

Wetting of cerium, lanthanum and scandium fluorides by Ga, In, Sn, Pb, Al, Ge, Ag, Au, Cu in an interval of temperatures 250–1100 °C in vacuum 2×10-3 Pa are investigated. Sessile drop method with application of capillary purification method of alloy during experiment was used. Wetting increase with rise of temperature. Interaction trace on contact boundary can be seen.
