Objective

Series: Solubility Data Series

This project includes compilations and critical evaluations for the solubility of rare earth metal fluorides in water and aqueous systems. This report continues the previous assessments dealing with rare earth metal halides in non-aqueous [1] and aqueous [2,3] solvents.

Description

A complete set of compilations will be prepared for the solubilities of all rare earth metal fluorides in water as well as in aqueous solutions containing other inorganic and organic substances. The set of compilations related to a selected metal will be introduced with a critical evaluation of all related solubility results, equilibrium solid phases and a selection of suggested solubility data.

The systems to be covered by this project fit within the priority focus area identified in the phantom proposal, Solubility Related to Industrial Processes.
