Eutectic alloy with Strontium & Lithium?

In summary, according to the two sources, an alloy including Strontium and Lithium at room temperature is possible, but there is no definitive information on where to find it.

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.
 

FAQ: Eutectic alloy with Strontium & Lithium?

What is a eutectic alloy?

A eutectic alloy is a mixture of two or more metals that has a lower melting point than any of its individual components. It is formed when the metals are mixed in specific proportions and undergo a eutectic reaction.

What is the role of strontium in a eutectic alloy with strontium and lithium?

Strontium is a common additive in eutectic alloys because it helps to lower the melting point and increase the fluidity of the mixture. In the case of a eutectic alloy with strontium and lithium, strontium acts as a modifier to the eutectic reaction between the two metals, resulting in a more stable and desirable alloy.

What are the properties of a eutectic alloy with strontium and lithium?

A eutectic alloy with strontium and lithium typically has a lower melting point, improved fluidity, and increased strength compared to its individual components. It is also known for its good castability and excellent corrosion resistance, making it a popular choice in various industrial applications.

What are the common uses of a eutectic alloy with strontium and lithium?

Eutectic alloys with strontium and lithium are commonly used in the automotive and aerospace industries for casting engine parts, such as pistons, valves, and crankshafts. They are also used in the production of electronic components and batteries due to their low melting point and good conductivity.

How is a eutectic alloy with strontium and lithium produced?

A eutectic alloy with strontium and lithium is typically produced through a process called alloying, where the metals are melted and mixed in specific proportions. The mixture is then cooled and solidified to form the desired alloy. The exact production process may vary depending on the specific application and requirements of the alloy.
