Abstract : Amongst the existing models able to describe highly concentrated aqueous systems and solid-liquid or gas-liquid equilibria up to elevated temperatures and pressures, the semi-empirical Pitzer model has been shown to be powerful. Calculation codes are now available for applying this model to such complex natural and industrial systems. The key point remains the building of related thermodynamic databases of high quality. In this work, we present elements of a strategy to build and extend such a database for widespread use.
