Gallium painted on to glass is an excellent mirror. Because of this as well as the steel contamination and freezing-expansion issues, samples of gallium metal are often equipped in polyethylene packets inside of other containers.
Gallium effortlessly alloys with numerous metals, and is Utilized in modest quantities in the plutonium-gallium alloy inside the plutonium cores of nuclear bombs to stabilize the plutonium crystal framework.[nine]
