Zircon extracted from beach sands contains about 2% hafnium oxide and traces of Al 2 O 3 (0.5%), Fe 2 O 3 (0.1%) and TiO 2 (0.1%). In addition, all zircons contain traces of uranium and thorium. Zircon is processed by fine grinding to produce a range of milled products of defined particle size.Giá năm 2021

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.Giá năm 2021

 · At high pressures, as determined by x-ray analysis, titanium and zirconium metal have a distorted, body-centered-cubic structure. This phase persists on pressure release. The normal hexagonal close-packed structures are recovered when the metals are heated. An electronic shift must occur in the transition. Hafnium metal showed no such transition.Giá năm 2021

Titanium, zirconium, and hafnium belong to the transition Group IV B elements of the periodic table. A characteristic feature of these transition elements is the ease with which they form stable complex ions. Features that contribute to this ability are favorably high charge‐to‐radius ratios and the availability of unfilled d orbitals.Giá năm 2021

Thus both zirconium and hafnium are rather poorly represented in oxidation states other than +4, and the ionic radii are Zr 4 + = 74 pm and Hf 4 + = 75 pm, leading to chemical properties that differ only in comparatively minor respects.Giá năm 2021
