Gadolinium Selenate,CAS : N/A
Product Code : Chem-Se009-CU-CU
E FORU specializes in producing high purity Gadolinium Selenate,CAS : N/A 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 ( 9 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..Selenates are analogous to sulfates and have similar chemistry. They are highly soluble in aqueous solutions at ambient temperatures.Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium.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,

Gadolinium(3+) triselenateIn strongly acidic conditions, the hydrogen selenate ion, HSeO−4, is formed. It corresponds to the selenic acid, H2SeO12, which is a strong acid and can in its concentrated form dissolve gold.The element selenium exhibits several valence states. Selenate is the least reduced, followed by selenite, and elemental selenium; selenide is even more reduced than elemental selenium.The valence state is an important factor to the toxicity of selenium. Selenate is the form required by organisms that need selenium as a micronutrient. These organisms have the ability to acquire, metabolize and excrete selenium.The level at which selenium becomes toxic varies from species to species and is related to other environmental factors like pH and alkalinity that influence the concentration of selenite over selenate.Selenate and other forms of selenium are highest in areas where ancient seas have evaporated. These areas are enriched in selenium and over millennia, biologic adaptation has occurred
