E FORU specializes in producing high purity Ammonium Metavanadate,CAS : 7803-55-6 with the smallest possible average grain sizes,Purities may include 99%, 99.9%, 99.99%, 99.999% and 99.9999%, which are sometimes referred to as 2N, 3N, 4N, 5N and 6N. 99.99995% (6N5), and in some cases up to 99.99999% (7N) and 99.999999% (8N),E FORU produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Our standard powder particle sizes average in the range of - 325 mesh, - 200 mesh,- 100 mesh, 10-50 microns and submicron ( 1 micron). We can also provide in the nanoscale range.Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas. a vanadate is an anionic coordination complex of vanadium. Often vanadate refers to oxoanions of vanadium, most of which exist in its highest oxidation state of +5. The complexes [V(CN)6]3− and [V2Cl9]4− are referred to as hexacyanovanadate(III) and nonachlorodivanadate(III), respectively.In chemical nomenclature when vanadate forms part of the name, it indicates that the compound contains an anion with a central vanadium atom,.Quality inspection department staff which uses atomic spectroscopy, x-ray diffraction analysis, scanning electron microscopy, glow discharge mass spectroscopy (GDMS), and BET surface area analysis, among other technologies, to ensure that the elemental composition and structural properties of each product rigorously adhere to our standards.Additional technical, research and safety (MSDS) information is available,

Ammonium monovanadate, ammonium m-vanadate, ammonium vanadate, ammonium vanadate(+5), ammonium vanadate (meta), ammonium vanadate(V), ammonium vanadium oxide, vanadic acid ammonium salt, ammonium trioxovanadate, CAS 11115-67-6A simple vanadate ion is the tetrahedral orthovanadate anion, VO3−4 (which is also called vanadate(V)), which is present in e.g. sodium orthovanadate and in solutions of V2O5 in strong base (pH > 13). Conventionally this ion is represented with a single double bond, however this is a resonance form as the ion is a regular tetrahedron with four equivalent oxygen atoms.Additionally a range of polyoxovanadate ions exist which include discrete ions and "infinite" polymeric ions. There are also vanadates, such as rhodium vanadate, RhVO4, which has a statistical rutile structure where the Rh3+ and V5+ ions randomly occupy the Ti4+ positions in the rutile lattice, that do not contain a lattice of cations and balancing vanadate anions but are mixed oxides.VO3−4 "orthovanadate", tetrahedral.V2O4−7 "pyrovanadate", corner-shared VO4 tetrahedra, similar to the dichromate ion,V3O3−9, cyclic with corner-shared VO4 tetrahedra,V4O4−12, cyclic with corner-shared VO4 tetrahedra,V5O3−14, corner shared VO4 tetrahedraV6O6−18, ring.V10O6−28 "decavanadate", edge- and corner-shared VO6 octahedra[2]V12O4−32V13O3−34, fused VO6 octahedra ,V18O12−42,Some examples of polymeric "infinite" ions are[VO3]n−n in e.g. NaVO3, sodium metavanadate[[V3O8]n−n in CaV6O17
