What will gallium melt in?
Elemental gallium is a liquid at temperatures greater than 29.76 °C (85.57 °F), and will melt in a person’s hands at normal human body temperature of 37.0 °C (98.6 °F). Gallium is predominantly used in electronics….

Where is gallium most commonly found?
Gallium usually cannot be found in nature. It exists in the earth’s crust, where its abundance is about 16.9 ppm. It is extracted from bauxite and sometimes sphalerite. Gallium can also be found in coal, diaspore and germanite.
What is liquid gallium used for?
Liquid gallium wets porcelain and glass surfaces; it forms a bright, highly reflective surface when coated on glass. It can be used to create brilliant mirrors. Gallium easily alloys with most metals, so it is used to form low-melting alloys.
What metals does gallium dissolve?
Ten surprising facts about gallium A small amount of gallium will destroy anything made out of aluminum, including aluminum cans. It also attacks steel, making it very brittle. Although it can melt in your hand, it won’t boil unless you heat it to 4,000F – the largest range of any element.
Why does gallium melt in your hand?
Like most other metals, Gallium is solid at room temperature (or liquid if it is too hot in your room). But, if it is held [in hands] for long enough, it melts in your hands, and doesn’t poison you like Mercury would. This is because of its unusually low melting point of (~29 degree Centigrade ).
How expensive is gallium?
Cost, pure: $220 per 100g. Cost, bulk: $ per 100g. Source: Gallium does not exist free in nature and there are no minerals with any substantial gallium content. Commercially, most gallium is extracted as a byproduct of aluminum and zinc production.
Why does gallium melt?
Even boiling water doesn’t melt it instantly. Because gallium is a metal, it conducts heat fairly well, so when heated gently, it won’t melt until the temperature of the whole piece gets close to the melting point.
Is gallium a metal nonmetal or metalloid?
Gallium is a silvery, glass-like, soft metal. It sits close to the non-metals in the periodic table and its metallic properties aren’t as obviously metallic as most other metals. Solid gallium is brittle and is a poorer electrical conductor than lead. The solid metal fractures conchoidally.
