The results obtained have fundamental scientific value and contain a number of new data, in particular concerning the dewetting phenomenon for the alloys, containing the titanium and other chemically active elements. Using new technique surface tension and density of some of the binary and multicomponent chemically active aggressive alloys containing large amounts of Ti, Zr were measured for the first time. Based on the analysis of data received the basic criteria concerning a degree of wetting in a liquid metal - ceramic material systems and also the thermodynamic and atomic-electron features of a structure of contact substances which provide a high degree of wetting and, if necessary, a low degree of wetting are formulated.Results of the work are used in technologies of materials soldering, manufacturing of composites and refractories resistant against chemically aggressive alloys (on base of fluorides), and use them for crucibles, containers, covers for thermocouples and other products making.
