About Antimonides

Antimonide Ion

Antimonides, also known as stibnides, are compounds of antimony with more electropositive elements. Many are flammable due to the reducing properties of the antimonide ion. Most commercially relevant antimonides are compounds of antimony with group II or III metals, and are semiconductors most often found in optoelectronic applications.

Notable antimonide semiconductors include gallium antimonide, indium antimonide, aluminum antimonide, and ternary alloys of these compounds with each other or with related semiconductors. Bismuth antimonide is notable for being the material in which 3D topological insulator properties were first observed. Hydrogen antimonide is also known as stibine, and is a toxic colorless gas analogous to arsine and phosphine. A number of relatively rare natural antimonide minerals exist, including the gold antimonide mineral aurostibite.

American Elements manufactures multiple forms of antimonide compounds including solutions, nanopowders, submicron, and -325 mesh powders, and high surface area materials with particle distribution and particle size controlled and certified. We also produce larger -40 mesh, -100 mesh, -200 mesh range sizes and <0.5 mm, 2 mm, 5 mm and other sizes of shot, granules, lump, flake and pieces. Purities include 99%, 99.9%, 99.99%, 99.999% and 99.9999% (2N, 3N, 4N, 5N and 6N).

American Elements maintains industrial scale production for all its antimonide products and will execute Non-Disclosure or Confidentiality Agreements to protect customer know-how.
