Abstract

Various values of surface tension of quartz have been given already but reliability of those values is very questionable.<BR>Author observed the surface tension of amorphous quartz fibre (radius 0.3-10μ) and found that the relation between radius and surface tension was shown as follows w=πr2σ+2πr·γ; w: weight which is necessary for breaking of quartz fibre; r: radius;σ: tensile strength;γ: surface tension The values of σ and γ of quartz fibre were found to be 65 kg/mm2 and 1348480 dyne/cm, respectively.
