Surface Phenomena And Interfacial Interaction At The Glass - Liquid Tin - Gas Phase Interface

The sessile drop method was used to study the temperature dependences of the density and surface tension of tin and liquid glass. The effect of the composition of the gas phase on the surface tension of the glass has been studied. The method of adjoining drops to determine the temperature dependence of the interfacial tension at the glass-tin melt boundary was used. The effect of silicon, aluminium, iron, nickel and manganese on the interfacial tension in the glass-tin system was also studied. It was shown that in this system, these additives are not interface-active.
