Summary[edit]

In the scientific publication "Gallium Safety in the Laboratory", L. C. Cadwallader states that "Galinstan ... boils at about 2300°C". The Material Safety Data Sheet published by Geratherm simply states that the boiling point of Galinstan is greater than 1300°C. The author of this diagram (Peter Dow) wonders if rather than boil from liquid galinstan into "gaseous galinstan", a dissociation of galinstan into its elements occurs at galinstan's boiling or dissociation temperature, namely gaseous gallium, gaseous indium and tin vapour which could condense into liquid tin at temperatures below the boiling point of tin? Or is there a stable temperature range for molecular gaseous galinstan above galinstan's boiling point and if so what is galinstan's dissociation temperature? Anyway, internet searches are not turning up much in the way of information about the boiling behaviour of galinstan so this diagram if nothing else can highlight the lack of published detail on this and if someone knows and wants to let the rest of us know, that would be kind. Thanks.

Boiling points of Gallium and Tin disagreements

For the first version of this diagram, I simply assumed the values for the boiling points of the elements which were given in the Wikipedia pages for the elements gallium, indium and tin would be about right.

There seems to be quite a wide variation in the values quoted in different books and websites. See the discussion pages for Gallium and Tin but we are talking hundreds of degrees of a difference. For example, one of my old text books gives different values there which correspond to the Chemical Elements website at first glance. On the other hand, another of my text books gives different values again.

These wide variations are not reflected in the tabulation of reference values on this wikipedia page - Boiling points of the elements (data page). I am discussing this here Talk:Boiling points of the elements (data page).

My web search found a very relevant scientific paper "The Vapor Pressure of Indium, Silver, Gallium, Copper, Tin, and Gold Between 0.1 and 3.0 Bar" by F. Geiger, C. A. Busse and R. I. Loehrke, published in "International Journal of Thermophysics, Vol. 8, No. 4, 1987"^{[dead link]} and this has inspired me to revise my diagram and to upload a second version.
