At room temperature, gallium metal is not reactive with air and water because it forms a passive, protective oxide layer. At higher temperatures, however, it reacts with atmospheric oxygen to form gallium(III) oxide, Ga 2 O 3. [34] Reducing Ga 2 O 3 with elemental gallium in vacuum at 500 °C to 700 °C yields the dark brown gallium(I) oxide ...
At room temperature, gallium metal is not reactive with air and water because it forms a passive, protective oxide layer. At higher temperatures, however, it reacts with atmospheric oxygen to form gallium(III) oxide, Ga 2 O 3.

Also, it is formed on heating gallium in air or by thermally decomposing gallium nitrate at 200–250 °C. Crystalline Ga 2 O 3 can occur in five polymorphs, α, β, γ, δ, and ε. Of these polymorphs β-Ga 2 O 3 is the most thermodynamically stable phase at standard temperature and pressure [ 14 ] while α-Ga 2 O 3 is the most stable ...
Liquid Metal may refer to: . A liquid metal, which has a relatively low melting point, such as mercury, tin or lead; Any metal in a liquid state; Mercury, the only metal to be liquid at room temperature
Galinstan is a brand name for an alloy composed of gallium, indium, and tin which melts at −19 °C (−2 °F) and is thus liquid at room temperature. [4] [5] In scientific literature, galinstan is also used to denote the eutectic alloy of gallium, indium, and tin, which melts at around +11 °C (52 °F). [5]
China on Tuesday banned exports to the United States of the critical minerals gallium, germanium and antimony that have widespread military applications, escalating trade tensions the day after ...

They all contain gallium in the +3 oxidation state. Their proper names are gallium(III) fluoride, gallium(III) chloride, gallium(III) bromide and gallium(III) iodide. GaF 3 GaF 3 is a white solid which sublimes before it melts, with an estimated melting point above 1000 °C. [contradictory] It contains 6 co-ordinate gallium atoms with a three ...
