An analysis is presented of the effects of electric fields on spinodal decomposition in a perfect dielectric material. The appropriate diffusion equation is derived for fields which oscillate slowly with time, and is solved for the early stages of decomposition. The theory is phenomenological and takes account of effects due to free energy changes with polarization and to field dependent mobilities. The results indicate that electric fields should generally act to inhibit spinodal decomposition at least in systems exhibiting positive curvature in the relation between dielectric constant and composition.
