Chromate Ion

Chromate is a rather strong oxidizing agent which contains the chromate anion, CrO42− . Chromates are used in chrome plating to imporve paint adhersion and to protect metals from corrosion.

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 carbonate 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.

American Elements maintains industrial scale production for all its chromates products.

American Elements will execute Non-Disclosure or Confidentiality Agreements to protect customer know-how.
