Variation of Surface Tension of Sodium Aluminate Solution with Electrolytic Microstructure
铝酸钠溶液结构改变时的表面张力变化

Surface tension of sodium aluminate and Si-containing sodium aluminate solutions was measured by the air bubble method. Effects of factors such as molar ratio, temperature, Si added and aluminate concentration on surface tension were investigated. The results are explained in terms of Raman spectra and the sub-molecular structure of electrolytic solution.
