He later isolated the metal by electrolysis. ." 18 Oct. 2020 . An alloy of gallium, indium, and tin (trade name Galinstan) is used in high-grade thermometers to replace the obviously problematic mercury. Watch the rotation video to see how delicate it is (and in fact it's cracked in several places, though it's still hanging together, implying that the metallization layers are strong enough to keep it intact even though the substrate is broken). Gallium is known for its low melting point, which lends itself to the gallium spoon demonstration and even melting the pure metal in your hand. Encyclopedia.com. Gallium is also used in small quantities as a plutonium crystal stabilizer in the plutonium cores of nuclear bombs. ." Asked by Wiki User. Here are some interesting facts about gallium.[2].
