An x-ray determination of the size distribution of wetting colloid particles

Abstract A means for colloidal solution characterization was sought in order to describe changes in the wetting properties of metal hydrosols with solution age and concentration. The size of the hydrosol particles was selected as a parameter which would depict the changes in the age and constituent concentration of the solutions. The technique of small angle x-ray scattering was applied to determining the in sol particle size distributions. The experimental and analytical details of the technique were verified by determining size distributions of colloidal particles which had been previously determnied elsewhere.
