Photon correlation spectroscopy of a coagulating suspension of illite platelets

Abstract

The self-beat intensity correlation spectra scattered from coagulating suspensions of illite platelets have been analysed to determine colloidal stability ratios. The stability ratio results as a function of KCI concentration were used to evaluate the effective Hamaker constant for the illite platelets. The effective Hamaker constant obtained by this method compares favourably with those obtained by direct measurement on crystallographically identical mica plates, either in KNO3 solution or, after applying the geometric mixing rule, in a vacuum.
