Zirconium Wikipedia

In this report, zirconium(IV)? and hafnium(IV)?bishydroxamic acid complexes were utilized in the highly enantioselective epoxidation of homoallylic alcohols and bishomoallylic alcohols, which used to be quite difficult substrates for other types of asymmetric epoxidation reactions.Zirconium and hafnium are contained in zircon at a ratio of about 50 to 1. Zircon is a coproduct or byproduct of the mining and processing of heavymineral sands for the titanium minerals, ilmenite and rutile, or tin minerals.

A zirconium sponge regulus from a Kroll reduction process is contaminated with zirconium chlorides, unreacted magnesium and magnesium chloride. R. James Adams Current Assignee (The listed assignees may be inaccurate. Google has not performed a legal analysis and makes no representation or warranty as to the accuracy of the list.).The PMR spectra of zirconium and hafnium borohydrides are similar in overall shape but significantly differ in their chemical shifts. Tiffs difference can apparently be explained by the influence of the electronic structure of the central metal atom, for example by the presence of a 4f shell in hafnium.Similar Items.

Hafnium, on the other hand, has an exceptionally high cross section, and accordingly even slight hafnium contamination nullifies the intrinsic advantage of the zirconium. Because of its high neutroncapture cross section and its excellent mechanical properties, hafnium is.Zirconium is a chemical element with symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon;zargun, "goldlike" or "as gold")), the most important source of zirconium. It is a lustrous, greywhite, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.Quantitative determination of hafnium in mixtures of zirconiumhafnium hexachloro alkali compounds by neutron activation analysis and Xray fluorescence C.
