Surface Tension of Some Liquid Oxides and Their Temperature Coefficients

Surface-tension data are reported for liquid Al2 O3, B2 O3, GeO2, P2 O5, and SiO2. Abnormal positive temperature coefficients for B2 O3, GeO2, and SiO2 are shown to be due mainly to changes in the liquid structure (dissociation) with temperature.
