Dispersion systems


Dispersion systems are systems containing at least two phases, with one phase being dispersed
in the other phase in the form of small particles.


14.1 Basic classification


A dispersed phase is referred to as thedispersion ratioordispersion phase. The phase
whose continuity remains preserved is referred to as thedispersion environment. Dispersion
systems may be classified using several criteria:



  • State of matter of the dispersion environment and the dispersion phase

  • Size of particles of the dispersion phase

  • Structure of the dispersion phase.
    Classification based on the phases state of matter is summarized in the following table:
