Reference Question of the Day

I received this question from a chemical engineering professor: What is the solubility of argon in molten sodium?

I checked the following book:



Gases in molten salts /volume editors, Reginald P.T. Tomkins, Narottam P. Bansal.Author: Tomkins, R. P. T.(Reginald P. T.)



It gave the solubility of argon in molten sodium salts, but not in sodium metal. So I searched Scifinder Scholar. I started searching on Argon as a substance and limited it to properties. I then refined it using solubility and molten sodium. I retrieved 8 hits, but from the abstract only one had the answer:



New Data on the Solubility of Inert Gases in Liquid Alkali Metals at High Temperature
By Shpil'rain, E. E.; Skovorod'ko, S. N.; Mozgovoi, A. G.
From High Temperature (Translation of Teplofizika Vysokikh Temperatur) (2002), 40(6), 825-831. Language: English, Database: CAPLUS
The soly. of helium, neon, argon, krypton, and xenon in molten lithium, sodium, potassium, rubidium, and cesium is calcd. in the ranges of temp. from 600 to 1500 K and pressure from 0.1 to 10 MPa. The calcd. data are compared, in comparable ranges of the parameters of state, with the results of the exptl. investigations available in the literature of the soly. of inert gases in liq. alkali metals.



The abstract doess not have the piece of data needed. We will have to retrieve the article to find the exact data required.
