ferro molybdenum Brokermet SL

Chemical Analysis Chemical element, symbol Mo, with atomic number 42 and atomic weight 95.94; it is one of the transition elements. Silver gray metal with a density of 10.2 g / cm3 (5907 oz / in3), melts at 2610 ° C (4730 ° F).

Molybdic acid, H2MoO4 (or MoO3.H2O), forms a stable series of normal salts, of the type M22 + MoO4, M2 + MoO4 and M23 + (MoO4) 3. Polymeric molybdates or isopolymolybdates can be formed by acidification of a molybdate solution or, in some cases, by heating normal molybdates. Hydrogen peroxide reacts with various molybdates to form a series of peroxyanionic compounds.

 

Another group of molybdenum compounds are the heteropolyelectrolytes, by far a fundamental family of salts and free acids: each member contains a complex and high molecular weight anion.

Molybdenum is found in many parts of the world, but few deposits are rich enough to guarantee cost recovery. Most of the moly comes from mines where its recovery is the primary objective of the operation. The remainder is obtained as a by-product of certain copper processing operations.

Molybdenum forms compounds in which it has oxidation states, 0, 2+, 3+, 4+, 5+, 6+. It has not been observed as an ionizable cation, but cationic species such as molybdenyl are known. Molybdenum chemistry is extremely complex and, with the exception of halides and chalcogenides, very few simple compounds are known.

 

Molybdenum dioxide and trioxide are the most common and stable oxides; other oxides described are metastable and are essentially laboratory species.

 

It is broad in stability and a series of compounds homologous with S, Se and Te, similar to oxides.
