Installation for determination of the wettability of a surface by high-temperature silicate melts

An experimental installation is developed to evaluate the high-temperature wettability of refractory materials using a test liquid — high-temperature silicate melts of slag and glass. The relevance of this assessment is substantiated. The wetting angle is determined by the sessile drop method. An example of measuring of the wetting angle of the test liquid on the surfaces of solids in a wide temperature range is given.
