Alloying gallium with other metals that have low melting points such as indium and tin, produces alloys that are liquid at room temperatures. For example Galinstan, an alloy of 68% gallium, 22% indium and 10% tin by weight, melts at a cool 11°C (51.8°F). Or Indalloy-46L, which melts at 8°C (46.4°F).

Galinstan, like other liquid metals, supercools very readily and often remains liquid to temperatures as low as -19°C. This is often mistakenly given as Galinstan’s freezing point. Like mercury, these metals are liquid at room temps. But unlike mercury, they aren’t particularly toxic.

One correction, regarding why graphite rods are used as a moderator in a nuclear reactor. The answer stated that the graphite slows down the neutron release. This is not technically true, I don’t think. It slows the speed of the neutrons that are released, which in turn makes them more susceptible to interacting with other uranium atoms. This ultimately increases the number of neutrons released overall eventually creating a sustained reaction called “the point of criticality”. Source- former nuclear engineer

Glad you find it useful and interesting!

Thanks for the kind words. This is my whole goal on writing such articles, spreading around the world how great chemistry is, I’m glad it helped!
