About Niobates

Rubidium Niobate

Niobates are salts containing an anionic grouping of niobium and oxygen. One of the most common niobates is lithium niobate, a compound of niobium, lithium, and oxygen. Single crystals of this compound are used in the production of optical waveguides, optical modulators, and various other linear and non-linear optical applications.

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