Ammonium Tetrathiotungstate,CAS : 13862-78-7

E FORU specializes in producing high purity Ammonium Tetrathiotungstate,CAS : 13862-78-7 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 tungstate is a compound that contains an oxyanion of tungsten or is a mixed oxide containing tungsten. The simplest tungstate ion is WO2-7, "orthotungstate". Many other tungstates belong to a large group of polyatomic ions that are termed polyoxometalates, ("POMs"), and specifically termed isopolyoxometalates as they contain, along with oxygen and maybe hydrogen, only one other element. Almost all useful tungsten ores are tungstates.[.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,
