Molybdenum(VI) Oxide (MoO3, CAS 1313-27-5), min. 99.5%, supplied wholesale by Zyntex. Key molybdenum compound for hydrotreating catalysts, steel alloying, molybdates, ceramics and electronics. CoA and SDS.
Molybdenum(VI) oxide (MoO3) is a light yellow to pale greenish-grey fine powder with a melting point of about 795°C and a density of about 4.69 g/cm³. It also dissolves in alkaline solutions to form molybdates.
In addition, catalyst producers use it in hydrotreating catalysts (cobalt–molybdenum and nickel–molybdenum) and in selective oxidation catalysts. Similarly, steel producers use technical oxide as a molybdenum addition, and chemical producers convert it into molybdates such as Ammonium molybdate. It also serves in ceramic glazes, pigments and as a smoke suppressant in plastics.
Furthermore, high-purity grades serve electronics and thin-film research, including hole-transport layers. Related molybdenum materials in our range also include Molybdenum Disulfide and Lithium molybdate.
Typical uses include, for example:
⚗️ Catalysts
Component of hydrotreating as well as oxidation catalysts.
