MAIN FACTORS AFFECTING THE STABILITY OF COLLOIDS

A general survey is given on the role that interparticular attraction forces play in the aggregative stability of colloidally dispersed syst ems. Special attention is paid to the disjoining pressure acting betwe en interlayers. The importance of recent results obtained by the autho r using the so-called flow ultramicroscope method is emphasized as the se data allow the interpretation of the kinetics of slow coagulation, not only in the initial stage as does Fuchs' theory, but also in the w hole of the process.
