In this work, we present various modelling approaches available for describing the chemical evolution of a solid polycrystalline system made of at least two phases: these phases can be insulating or conducting, they can be corroded in aggressive environments, or react together at high temperature. Generally, in the case of heterogeneous systems, Avrami models seem to be well adapted to interpret the experimental data. To follow the chemical evolutions as a function of time or composition, we make use of a main technique the electrical complex impedance spectroscopy (ECIS) in a large frequency range (from 10 to the -1 to 10 to the 7 Hz).
