1.1 Geometric models

Geometric models apply to the chemical transformation of a solid made up either of a single particle or of a set of particles; these particles, also known as grains, must be dense. The transformation process involves the two processes of germination and growth, each with its own mechanism.

According to [P 3 775] , the growth mechanism takes on particular importance, as it is usually one of its steps, called the determining step, that is assumed to control the overall reaction rate (§ 1.4 of [P 3 775] ). In this case, whatever the determining...
