Formation of Liesegang patterns: A spinodal decomposition scenario
arXiv:cond-mat/9903420 · doi:10.1103/PhysRevLett.83.2880
Abstract
Spinodal decomposition in the presence of a moving particle source is proposed as a mechanism for the formation of Liesegang bands. This mechanism yields a sequence of band positions x_n that obeys the spacing law x_n~Q(1+p)^n. The dependence of the parameters p and Q on the initial concentration of the reagents is determined and we find that the functional form of p is in agreement with the experimentally observed Matalon-Packter law.
