Ammonium octamolybdate

Description

Ammonium octamolybdate, (NH4)4Mo8O26 or "AOM," is a commercially-useful molybdenum composition and is available in a variety of phases or isomers. The chemical compound referred to as ammonium octamolybdate is also commonly known variously as "diammonium catena-tetramolybdate," "ammonium tetramolybdate," "tetrammonium hexamolybdate," or by CAS number 12411-64-2. While α-AOM is commonly used as a smoke suppressant in various types of plastic materials, it may also be used in the formation of various types of optically-markable ink compositions. Such ink compositions change color in response to irradiation from light, typically from a laser, although other light sources may be used. The color change is the result of a change in oxidation state and/or the formation of non-stoichiometric products of the AOM constituent of the ink composition.

Uses

Ammonium octamolybdate is a molybdenum-based coordination compound used as a modifier for its flame-retardant properties, such as in the patented preparation of flame retardant and wear-resistant foamed asphalt. After modification of ammonium octamolybdate from its cluster geometry to a one-dimensional coordination polymer, ammonium octamolybdate is used as an olefin epoxidation catalyst.

Application

For industrial usage, plastic flame retardants, used in nylon, rubber, resin.
