Separation of Zirconium and Hafnium: A Review

Zirconium is an ideal material for nuclear reactors due to its low absorption cross-section for thermal neutrons, whereas the typically contained hafnium with strong neutron-absorption is very harmful for zirconium. This paper provides an overview of the processes for separating hafnium from zirconium. The separation processes are roughly classified into hydro- and pyrometallurgical routes

Zirconium and Hafnium Statistics and Information

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 heavy-mineral sands for the titanium minerals, ilmenite and rutile, or tin minerals. The major end uses of zircon are refractories, foundry sands (including investment casting), and ceramic opacification. Zircon is also marketed as a natural gemstone

Etching of zirconium oxide, hafnium oxide, and hafnium

Oxides and silicates of zirconium and hafnium are actively being considered and tested to replace SiO 2 as the gate material. Though these materials have the high-dielectric constant (k ∼ 20–25) needed to provide a larger equivalent oxide thickness, they are very refractory and difficult to etch by wet and dry methods. In this paper, work done on wet etching of ZrO 2, HfO 2, and HfSi x O y

Of the elements within d-block, zirconium has the fourth lowest electronegativity after yttrium, lutetium and hafnium. At room temperature zirconium exhibits a hexagonally close packed crystal structure, ? -Zr, which changes to ? Zr a body-centered cubic crystal structure at 863 °C. Zirconium exists in the ? -phase until the melting point. ZrZn2 is one of only two substances to exhibit

Zirconium and hafnium metals, like titanium, are hard and resistant to corrosion. These metals resemble stainless steel in appearance with melting points of 1855 and 2222 °C respectively. Heating zircon sand in the presence of graphite in an electric furnace forms the carbides. The ZrC (zirconium carbide) that's produced is reacted with chlorine to produce ZrCl
