About Arsenates

Arsenate Ion

Arsenates are salts or esters of arsenic acid. The arsenic atom in arsenate is also known as pentavalent arsenic or As(V) and has a valency of 5. Arsenates are moderate oxidizers, with a potential of +0.56 for reduction to arsenites. Arsenates are chemically similar the more well-known phosphates in many respects, and this similarity is responsible for the mechanism of arsenic toxicity: in biological systems, substitution of arsenate for inorganic phosphate disrupts essential biochemical pathways. A number of naturally occurring minerals, including the iron mineral scorodite, are arsenates. Arsenates are frequently used commercially as insecticides or preservatives.

American Elements manufactures multiple forms of arsenate 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 arsenate products and will execute Non-Disclosure or Confidentiality Agreements to protect customer know-how.
