TMP team – Solubility and Cristallisation phenomena

Partnairs : Christelle GOUTAUDIER (Resp.), Jean-Jacques COUNIOUX, Lobna MANOUBI

The aim of the Solubility and Crystallization Phenomena activity is to study the equilibrium conditions (P, T, x) of the different phases of a thermodynamic system in order to control complex chemical systems. The studies are focused mainly on inorganic solid phases and their precipitation in solution (aqueous or organic medium). They have multiple applications in many synthesis or separation processes involving solid / liquid equilibria: inorganic synthesis, crystal growth, extraction, purification, in close relationship with the industrial environment.
