About Scandium(III) Nitrate Hydrate

High purity Scandium(III) Nitrate Hydrate Nitrate IonScandium(III) Nitrate Hydrate is a moderately water soluble crystalline Scandium source that decomposes to Scandium oxide on heating. It is generally immediately available in most volumes. Acetates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials. All metallic acetates are inorganic salts of a metal cation and the acetate anion. The acetate anion is a univalent (-1 charge) polyatomic ion composed of two carbon atoms ionically bound to three hydrogen and two oxygen atoms (Symbol: CH3COO) for a total formula weight of 59.05. Ultra high purity, high purity, submicron and nanopowder forms may be considered. Nitrate compounds are generally soluble in water. Nitrate materials are also oxidizing agents. When mixed with hydrocarbons, nitrate compounds can form a flammable mixture. Nitrates are excellent precursors for production of ultra high purity compounds and certain catalyst and nanoscale (nanoparticles and nanopowders) materials. All metallic nitrates are inorganic salts of a given metal cation and the nitrate anion. The nitrate anion is a univalent (-1 charge) polyatomic ion composed of a single nitrogen atom ionically bound to three oxygen atoms (Symbol: NO3) for a total formula weight of 62.05. American Elements 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. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

See more Nitrogen products. Nitrogen is a Block P, Group 15, Period 2 element. Its electron configuration is [He]2s22p3. Nitrogen is an odorless, tasteless, colorless and mostly inert gas. It is the seventh most abundant element in the universe and it constitutes 78.09% (by volume) of Earth's atmosphere. Nitrogen was discovered by Daniel Rutherford in 1772.


See more Scandium products. Scandium (atomic symbol: Sc, atomic number: 21) is a Block D, Group 3, Period 4 element with an atomic weight of 44.955912. The number of electrons in each of Scandium's shells is [2, 8, 9, 2] and its electron configuration is [Ar] 3d1 4s2. Scandium Bohr Model The scandium atom has a radius of 162 pm and a Van der Waals radius of 216 pm.Scandium was predicted by Dmitri Mendeleev in 1871 and actually discovered and isolated by Lars Nilson in 1879. One of the transition metals, scandium has a silvery-white appearance in its elemental form which oxidizes to yellow or pinkish upon contact with air. Elemental ScandiumIt is occasionally included in the classification of the rare earth elements. Scandium is found in concentrated amounts in the minerals euxenite, gadolinite and thortveitite however, due to the difficulties in the preparation of metallic scandium, global trade of the pure metal is very limited. The origin of the name scandium comes from the Latin word 'scandia' meaning Scandinavia.
