Surface Tension of Some Liquid Oxides and Their Temperature Coefficients

Abstract

Surface‐tension data are reported for liquid Al 2 O 3 , B 2 O 3 , GeO 2 , P 2 O 5 , and SiO 2 . Abnormal positive temperature coefficients for B 2 O 3 , GeO 2 , and SiO 2 are shown to be due mainly to changes in the liquid structure (dissociation) with temperature.
