Title: Non-metals in liquid alkali metals
Series: Solubility Data Series
Task Group: Cezary
Guminski and Hans
Completion Date: 2001 - project completed
To compile and critically evaluate the solubility data for non-metals
in molten alkali metals.
All available solubility data of non-metallic elements and some
of their compounds in the five liquid alkali metal solvents (Li, Na,
K, Rb and Cs) are collected and compiled. Original publications with
reliable data and information on the methods used to generate them are
reported in individual COMPILATIONS. When numerical
data are not given in a publication, the data are often read-out from
figures and converted into numerical data by the compilers. The precision
of this procedure is indicated in the COMPILATIONS
under ESTIMATED ERROR. Evaluated solubility data
are tabulated at the end of the CRITICAL EVALUATIONS:
if there is agreement of at least two independent studies within the
experimental error, the solubility values are assigned to the "recommended"
category. Values are assigned as "tentative", if only one reliable result
was reported, or if the mean value of two or more reliable studies was
outside the error limits. In the tabulation, three, two, or one significant
figures are assigned for respective precisions that are better than
± 1 and ± 10 % and worse than ± 10 %. If necessary, the solubilities
are recalculated into mol %. The completeness of this investigation
of the literature has been confirmed and extended by studying several
reviews dealing with the solution chemistry of substances in the alkali
metals. Solubility data are sometimes measured under parameters which
are not standard conditions of such measurements. Frequently measurements
are performed under constrained pressure. The solubility of noble gases
or other gases which do not form compounds with the alkali metals depends
on the gas pressures.
