Aluminium antimonide

Aluminium antimonide (AlSb) is a semiconductor of the group III-V family containing aluminium and antimony. The lattice constant is 0.61 nm. The indirect bandgap is approximately 1.6 eV at 300 K, whereas the direct band gap is 2.22 eV.

Hazards
NFPA 704 (fire diamond)
Health 0: Exposure under fire conditions would offer no hazard beyond that of ordinary combustible material. E.g. sodium chlorideFlammability 3: Liquids and solids that can be ignited under almost all ambient temperature conditions. Flash point between 23 and 38 °C (73 and 100 °F). E.g. gasolineInstability 1: Normally stable, but can become unstable at elevated temperatures and pressures. E.g. calciumSpecial hazards (white): no code

Its electron mobility is 200 cm²·V−1·s−1 and hole mobility 400 cm²·V−1·s−1 at 300 K. Its refractive index is 3.3 at a wavelength of 2 μm, and its dielectric constant is 10.9 at microwave frequencies.[1]

AlSb can be reacted with other III-V materials to produce ternary materials including AlInSb, AlGaSb and AlAsSb.

Aluminium antimonide is rather flammable because of the reducing tendency of the antimonide (Sb3−) ion. It burns to produce aluminium oxide and antimony trioxide.
