Objective:
This project includes compilations and critical evaluations for
the solubility of rare earth metal (Sc, Y, La and all Ln) chlorides
in water and aqueous systems. This report supplements the previous elaboration
[1] dealing with rare earth metal chlorides in
non-aqueous solvents.

Description:
A complete set of compilations will be prepared for the solubilities
of all rare earth metal chlorides in water, aqueous solutions of hydrochloric
acid, salts and organic compounds. The set of compilations related to
a selected metal will be introduced with a critical evaluation of all
related results, a schema of partial phase diagram of the binary LnCl3-H2O
system and a selection of suggested solubility data. Only simple salts
of type LnCl3 (hydrates but no complexes of Ln), used as input
substances, are treated in this report.
Rare earth metal chlorides are very important substances used to production
of inorganic compounds and alloys as well as as catalysts in various
organic syntheses. The systems to be covered by this project fit within
the priority focus area identified in the phantom proposal, Solubility
Related to Industrial Processes.
