Abstract

Wetting of alkaline-earth metal fluorides by metallic melts with additives of elements with high affinity to electron is investigated. The dissolved oxygen in copper and copper - silver melts appreciably influences on adhesive properties of alloys to fluorides. Wettability improves at dissolution of small additives of oxygen. The received results are explained proceeding from the wetting chemical theory
