Solubility Products and Thermodynamic Functions for the Lanthanon Fluoride Water-Systems: Technical Progress Report

摘要

The solubility and the solubility product of GdF sub 3 were remeasured using both conductometric and potentiometric methods after careful washing of the precipitate and drying. Radiometric techniques were also employed for the measurement of the solubility of both GdF sub 3 and SmF sub 3 . In addition solubilities of the ytterbium trifluoride (YbF sub 3 ) and praseodymium trifluoride (PrF sub 3 ) were measured by conductometric method as a function of temperature. The measurement of the solubility of YbF sub 3 by radiochemical technique was completed. (ERA citation 12:025387)
