Surface Phenomena and Interfacial Interaction at the Glass–Liquid Tin–Gas Phase Interface

We used the sessile drop method to study the temperature dependences of the density and surface tension of tin and liquid glass. We have studied the effect of the composition of the gas phase on the surface tension of the glass. We used the method of adjoining drops to determine the temperature dependence of the interfacial tension at the glass horbar; tin melt boundary. We have studied the effect of silicon, aluminum, iron, nickel, and manganese on the interfacial tension in the glass ― tin system. We have shown that in this system, these additives are not interface-active.
