Zirconium. ATI was the first industrialized manufacturer of zirconium. In the late 1950s, ATI zirconium products were used for the nation's first full-scale commercial nuclear power plant, built in Shippingport, Pennsylvania, USA. Not only is ATI a pioneer in zirconium, today it is also a leader in zirconium metallurgy. Zirconium Chemicals

Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in many zirconium minerals.Its existence was predicted by Dmitri Mendeleev in 1869, though it was not identified until 1923, by Coster and Hevesy, making it the last stable element to be discovered.
We also produce gallium, indium, niobium, tantalum, rhenium and hafnium products. Neo Performance Materials also offers rare earth-based wastewater treatment solutions. Our proprietary rare earth chloride solution is a high performance, water-soluble coagulant that has a very strong attraction to phosphorus.

Apr 15, 2019· Hafnium: Hafnium (Hf), chemical element (atomic number 72), metal of Group 4 (IVb) of the periodic table. It is a ductile metal with a brilliant silvery lustre. The Dutch physicist Dirk Coster and the Hungarian Swedish chemist George Charles von Hevesy discovered (1923) hafnium in …
The pure zirconium or hafnium oxide is mixed with fine coke and react ed with chlorine to produce the tetrachloride gas. The pure zirconium or hafnium tetrachloride is then recovered in condensers. 10 Reduction The zirconium tetrachloride and hafnium tetrachloride are reduc ed to their respective metals in a batch process
It was named hafnium. It came from the Latin name of Hafnia in Copenhagen. In 1925, Hervey and Coster separated zirconium and titanium by fractional crystallization of fluorinated complexes to obtain pure hafnium salts, and reduced hafnium salts with sodium metal to obtain pure metal hafnium. Hervsi made several samples of pure hafnium.
Hafnium is a shiny silvery, ductile metal that is corrosion resistant and chemically similar to zirconium. The properties of hafnium are markedly affected by zirconium impurities and these two elements are amongst the most difficult to separate. The only notable difference between them is their density (zirconium is about half as dense as hafnium).
The hafnium crystal bar with low-impurity content was prepared by the iodide process using the raw hafnium (nuclear level hafnium sponge, electrolytic hafnium pow- der, and hafnium turnings), iodine (99.8 %), and hafnium filament (99.0 %) as raw materials.
