The formation and growth of colloidal particles of silica and alumina were examined by light scattering and size exclusion chromatography. For silica, condensation of primary particles was found to be a two-step process represented by a first-order kinetic equation. Polymerization of A1(III) ions was largely influenced by temperature and concentration of sulphate ions.
