Gallium does not occur as a free element in nature, but rather as gallium(III) compounds in trace amounts in zinc ores (such as sphalerite) and in bauxite. 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).
Indium gallium arsenide (InGaAs) and gallium-indium arsenide (GaInAs) are used interchangeably. According to IUPAC standards [2] the preferred nomenclature for the alloy is Ga x In 1-x As where the group-III elements appear in order of increasing atomic number, as in the related alloy system Al x Ga 1-x As.
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 ...
