Understanding Hydrogen in Zirconium
Selected examples of the Canadian contribution to the development of understanding of the behavior of hydrogen in zirconium alloys are reviewed. To solve the technical problems faced by the nuclear industry, it was necessary to have values for the solubility and diffusivity of hydrogen in the alloys, the diffusivity needed for the three gradients of concentration, temperature, and stress. With ...
متن کاملZirconium facts at your fingertips
Thanks to the Kroll process, metallic zirconium can be produced by means of a fairly complicated reduction process. In actual fact, the ore is found as a by-product when mining titanium and tin ore. Since 2003, the price of zirconium has more than doubled. This is the result of increasing demand and also the fact that a considerable amount of energy is needed to release zirconium from its chemi...
متن کاملMetallic residues after hydriding zirconium
As a part of the production of nitride nuclear fuel for use in fast nuclear reactors, zirconium is hydrided followed by nitriding and mixing with uranium nitride. This work concludes a study of unwanted metallic particles present in a powder that is supposed to be a zirconium hydride. Sponge zirconium was hydrided at different temperatures and different time intervals, and the resulting hydride...
متن کاملZirconium(IV) dilanthanum(III) pentasulfide
Zirconium(IV) dilanthanum(III) penta-sulfide, ZrLa(2)S(5), crystallizes with four formula units in the space group Pnma in the U(3)S(5) structure type. The asymmetric unit comprises one Zr, one La and four S atoms. The Zr and three S atoms are situated on mirror planes. The structure consists of LaS(8) face-sharing bicapped distorted trigonal prisms and ZrS(7) edge-sharing monocapped octa-hedra.
متن کاملPhosphonate-substituted zirconium oxo clusters
ABSTRACT The phosphonate-substituted zirconium oxo clusters Zr6O2(OBu)12(O3PPh)4 and Zr7O2(OiPr)12(O3PCH2CH2CH2Br)6, with octahedrally coordinated Zr atoms, were synthesized by reaction of zirconium alkoxides with phosphonic acid bis(trimethylsilyl) esters. The basic structural motif are Zr3O(µ2-OR)3(OR)3 units which are connected in different ways. GRAPHICAL ABSTRACT
