Abstract: | This paper discusses a theory for a new effect, the migration of solid dispersed particles initiated by a nonuniform temperature
field. The reason for the motion is the inhomogeneity of the properties of a thin protective layer around a particle. The
example of ionic dispersion shows that the sign of the coefficient of thermodiffusion depends on the magnitude of the electrostatic
potential at the particle surface and the thickness of the Debye layer and that the coefficientis larger than the values known
for molecular systems by a factor of 100 to 10000. In contrast to molecular systems, in disperse systems thermodiffusion should
play a much more important role.
