E FORU specializes in producing high purity Nickel Tellurate,CAS : 15852-21-8 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.tellurate is a compound containing an oxyanion of tellurium where tellurium has an oxidation number of +6. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom.Historically the name tellurate was only applied to oxyanions of tellurium with oxidation number +6, formally derived from telluric acid Te(OH)6,The metatellurate ion TeO2−4 is analogous to the sulfate ion, SO2−4 and the selenate ion, SeO2−4. Whereas many sulfates and selenates form isomorphous salts the tetrahedral metatellurate ion is only found in a few compounds such as the tetraethylammonium salt (NEt4)2TeO4.Compounds containing the octahedral TeO6−6 anion are known, these include Ag6TeO6, Na6TeO6 and Hg3TeO11 Many compounds with a stoichiometry that suggests the presence of a metatellurate ion actually contain poly.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,

Nickel tellurate, Nickel tellurium tetraoxide, Telluric acid (H2TeO4), nickel(2+) salt (1:1)Tellurium has two NMR active nuclei, 123Te and 125Te. 123Te has an abundance of 0.9% and a nuclear spin (I) of 1/2. 125Te has an abundance of 7% and an equivalent nuclear spin.125Te is more commonly performed because it has a higher sensitivity.The metatellurate anion has a chemical shift around 610 ppm when analyzed using 125Te NMR at 25 °C at a frequency of 94.735 MHz and referenced externally against aqueous 1.0 M telluric acid.Sulfur(VI) oxyanions have a coordination number of 4 and in addition to the tetrahedral sulfate ion, SO2−4, the pyrosulfate, S2O2−7, trisulfate, S3O2−10 and pentasulfate S5O2−16 ions all contain 4-coordinate sulfur and are built from corner-shared {SO4} tetrahedra. Selenate compounds include many examples of four coordinate selenium, principally the tetrahedral SeO2−4 ion and the pyroselenate ion, Se2O2−7 which has a similar structure to the pyrosulfate ion.[Unlike sulfur there are examples of a 5-coordinate selenium oxyanion, SeO4−
5 and one example of SeO6−11，
