Nitrate IonHafnium Nitrate is a moderately water soluble crystalline Hafnium source that decomposes to Hafnium 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.

Hafnium (Hf) atomic and molecular weight, atomic number and elemental symbol Hafnium (atomic symbol: Hf, atomic number: 72) is a Block D, Group 4, Period 6 element with an atomic weight of 178.49. Hafnium Bohr ModelThe number of electrons in each of Hafnium's shells is 2, 8, 18, 32, 10, 2 and its electron configuration is [Xe] 4f14 5d2 6s2. The hafnium atom has a radius of 159 pm and a Van der Waals radius of 212 pm. Hafnium was predicted by Dmitri Mendeleev in 1869 but it was not until 1922 that it was first isolated Dirk Coster and George de Hevesy.Elemental Hafnium In its elemental form, hafnium has a lustrous silvery-gray appearance. Hafnium does not exist as a free element in nature. It is found in zirconium compounds such as zircon. Hafnium is often a component of superalloys and circuits used in semiconductor fabrication. Its name is derived from the Latin word Hafnia, meaning Copenhagen, where it was discoveredFor more information on hafnium, including properties, safety data, research, and American Elements' catalog of hafnium products, visit the Hafnium Information Center.
