Application

Ammonium octamolybdate (AOM), also known by various names like "diammonium catena-tetramolybdate" and "tetrammonium hexamolybdate," is a versatile molybdenum-based compound with a range of industrial applications. It serves primarily as a smoke suppressant in plastic materials, enhancing their safety and performance. Additionally, AOM is integral in the development of optically-markable ink compositions that exhibit color changes upon exposure to light, including laser irradiation. This color change is due to alterations in the oxidation state or the formation of non-stoichiometric products within the AOM structure. Furthermore, AOM's utility extends to its role as a flame-retardant agent in the production of wear-resistant foamed asphalt, as well as its application as a catalyst in olefin epoxidation processes, underlining its significance in both safety advancements and chemical manufacturing.
