The physical properties of gallium are highly anisotropic, i.e. have different values along the three major crystallographic axes a, b, and c (see table), producing a significant difference between the linear (α) and volume thermal expansion coefficients. The properties of gallium are strongly temperature-dependent, particularly near the ...
Gallium trichloride is a common starting reagent for the formation of organogallium compounds, such as in carbogallation reactions. [15] Gallium trichloride reacts with lithium cyclopentadienide in diethyl ether to form the trigonal planar gallium cyclopentadienyl complex GaCp 3. Gallium(I) forms complexes with arene ligands such as ...

Gallium is a chemical element in the periodic table that has the symbol Ga and atomic number 31. A rare, soft silvery metallic poor metal , gallium is a brittle solid at low temperatures but liquefies slightly above room temperature and indeed will melt in the hand.
Gallium nitride (Ga N) is a binary III/V direct bandgap semiconductor commonly used in blue light-emitting diodes since the 1990s. The compound is a very hard material that has a Wurtzite crystal structure. Its wide band gap of 3.4 eV affords it special properties for applications in optoelectronics, [9] [10] [11] high-power

Gallium can be anodically dissolved in perrhenic acid at 50-55 °C, and dried with sulfuric acid to obtain the hydrate crystal [Ga(H 2 O) 6 (ReO 4) 3]·2H 2 O. [2] The anhydrous form can be obtained by reacting gallium(III) oxide and rhenium(VII) oxide at 450 °C.
