The blistering phenomenon in zirconium and zirconium alloys

Corrosion Science, 1993
In this paper, the phenomenon of blistering on zirconium, Zircaloy-4 and in particular Zircaloy-2, has been investigated. The base solution was CH3OH/HCl, but some experiments were also performed in CH3OH/I2 solutions. The effects of environmental variables, including acid concentration, cathodic poisons and applied potentials, were investigated ...

Ultrathin 2D Zirconium Metal-Organic Framework Nanosheets: Preparation and Application in Photocatalysis.

Small, 2018
Synthesizing ultrathin 2D metal-organic framework nanosheets in high yields has received increasing research interest but remains a great challenge. In this work, ultrathin zirconium-porphyrinic metal-organic framework (MOF) nanosheets with thickness ...

Systems Zirconium-Molybdenum and Zirconium-Wolfram

JOM, 1953
On the basis of metallographic analysis, incipient melting data, thermal analysis work, and X-ray diffraction, phase relationships in the 0 to 50 atomic pct alloy content were carefully resolved. Phase relationships in the higher alloy content regions were outlined. A single intermediate phase, peritectically formed, of the form ZrX2 was established in

Unusual and highly tunable missing-linker defects in zirconium metal-organic framework UiO-66 and their important effects on gas adsorption.

Journal of the American Chemical Society, 2013
UiO-66 is a highly important prototypical zirconium metal-organic framework (MOF) compound because of its excellent stabilities not typically found in common porous MOFs.

Electrowinning of zirconium from zirconium tetrachloride

Metallurgical Transactions, 1972
The Bureau of Mines has produced ductile zirconium dendrites at 800°C in an electrolyte containing NaCl-NaF-ZrCl4. Sublimed zirconium tetrachloride was fed into NaCl containing a slight excess of NaF above that required to complex 2 pct Zr as Na2ZrF6. The chlorine gas generated at the graphite anode during electrolysis was confined in and vented out of

Encapsulation of a Nerve Agent Detoxifying Enzyme by a Mesoporous Zirconium Metal-Organic Framework Engenders Thermal and Long-Term Stability.

Journal of the American Chemical Society, 2016
Immobilized enzymes typically have greater thermal and operational stability than their soluble form. Here we report that for the first time, a nerve agent detoxifying enzyme, organophosphorus acid anhydrolase (OPAA), has been successfully encapsulated ...

Zirconium in the Ecology

American Industrial Hygiene Association Journal, 1973
The negligible interaction of living species with zirconium compounds that have existed in the earth's crust and waters is analyzed and discussed. Zirconium is shown to be a non-toxic element, the chemical behavior of which has made it unsuitable for roles in the structures of living organisms or in their biochemical processes.
