Gallium hydroxide, Ga(OH)3, is the normal mineral form of gallium in the Earth's crust.
Gallium hydroxide is not seen as a discrete mineral; rather, gallium replaces aluminium in ores such as bauxite. Rich sources may contain almost 1% Ga replacing Al, but a more typical value is a hundred times less.
Gallium hydroxide is amphoteric. In strongly acid conditions, gallium ion, Ga3+ is formed; in strongly basic conditions, Ga(OH)4-, is formed.
Salts of Ga(OH)4- are sometimes called gallates.
The liquid range for this metal is the largest liquid range of any known element, meaning it can be used in thermometers in extreme high temperatures.[citation needed]
