AI Thread Summary
A user is seeking a eutectic liquid alloy containing Strontium and Lithium that operates near room temperature. The discussion highlights the availability of the Lithium-Strontium binary phase diagrams through ASM International, which provide detailed information on the phase relationships and temperature ranges for these elements. Two specific diagrams are referenced: one based on a 1994 study showing a concentration range of 0-16 at.% Strontium at temperatures between 120°C and 190°C, and another from 1990 covering a broader range of 0-100 at.% Strontium at temperatures from 100°C to 800°C. The user is advised to conduct their own tests due to potential discrepancies in phase maps. Ultimately, they express disappointment in discovering that the Lithium-Strontium system does not meet their needs as an alternative to Mercury and Galinstan for a room temperature eutectic alloy.

Hello! I am looking for a eutectic (liquid) alloy that includes Strontium and Lithium at or near room temperature. Does anyone have an idea of where to look for it? Thanks!
 
Do you have any reason to believe that such an alloy exists?

If one is looking for a binary phase diagram, one would be able to find Sr-Li phase diagram through ASM International in their alloy phase diagram database.

I recommend performing one's own test with regard to phases in the temperature and pressure ranges of interest, since I have found conflicting maps in other systems.
 
Thanks for the inputs. We were looking for an eutectic alloy alternative to Mercury and Galinstan at room temperature and obviously were misled into thinking the Lithium-Strontium system had such properties.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
I'm trying to find a cheap DIY method to etch holes of various shapes through 0.3mm Aluminium sheet using 5-10% Sodium Hydroxide. The idea is to apply a resist to the Aluminium then selectively ablate it off using a diode laser cutter and then dissolve away the Aluminium using Sodium Hydroxide. By cheap I mean resists costing say £20 in small quantities. The Internet has suggested various resists to try including... Enamel paint (only survived seconds in the NaOH!) Acrylic paint (only...
