An arsenide is any member of a rare mineral group consisting of compounds of one or more metals with arsenic (As). It is an anion with the charge −3. The trianion is formed by the reduction of arsenic by three electrons. For example heating arsenic powder with excess sodium gives sodium arsenide (Na3As). The anions have no existence in solution since they are extremely basic. These solid salts have very high lattice energies.

Arsenides are toxic because of the inherent toxicity of arsenic and all of its compounds. Aluminum arsenide is a semiconductor material. Gallium arsenide is an important semiconductor, and is used in the manufacture of devices such as microwave frequency integrated circuits, monolithic microwave integrated circuits, infrared light-emitting diodes, laser diodes, solar cells, and optical windows. Quantum dots can be formed in a monolayer of indium arsenide on gallium arsenide.

Cadmium arsenide can be prepared as amorphous semiconductive glass, used in infrared detectors using Nernst effect, and in thin-film dynamic pressure sensors. It can be also used to make magnetoresistors, and in photodetectors. Cadmium arsenide can be used as a dopant for HgCdTe.

Indium arsenide is a semiconductor with the appearance of grey cubic crystals and a melting point 942 °C. Indium arsenide is used for construction of infrared detectors. The detectors are usually photovoltaic photodiodes. Cryogenically cooled detectors have lower noise, but indium arsenide detectors can be used in higher-power applications at room temperature as well. Indium arsenide is also used for making of diode lasers.

Purities include 99%, 99.9%, 99.99%, 99.999% and 99.9999% which are sometimes referred to as 2N, 3N, 4N, 5N and 6N.

Physical properties may include nanopowder, nano particle, submicron, - 325 mesh, rod, foil, and high surface area bromide with particle distribution and particle size controlled and certified. We produce larger - 40 mesh, - 100 mesh, -200 mesh range sizes and < 0.5 mm, 2 mm, 5 mm and other mm size shot, granules, lump, flake and pieces, too.
