Project No.:
Start Date:
01 October 2010
End Date:
01 October 2013


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

A complete set of compilations will be prepared for the solubilities of all rare earth metal bromides and iodides in water as well as in aqueous solutions containing 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.

Rare earth metal bromides and iodides have an increasing importance in production of mercury-free lamp fillings, materials used in spectroscopy, corrosion protection and catalysis of polymerization and various organic reactions.

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