Comment on “Oxidation of Hafnium and Diffusion of Hafnium Atoms
In his paper, Chandi C. Dey reports on the measurement of the nuclear quadrupole interaction of 181Hf(β−)181Ta in α-Hf metal with a few percent zirconium heated in air by perturbed angular correlation (PAC) of γ-rays. Since he did not observe the formation of HfO2 up to 773 K and during initial heating at 873 K for one day, he concluded that no oxygen is absorbed. The time dependent hyperfine i...
متن کاملExploiting the Brønsted Acidity of Phosphinecarboxamides for the Synthesis of New Phosphides and Phosphines
We demonstrate that the synthesis of new N-functionalized phosphinecarboxamides is possible by reaction of primary and secondary amines with PCO(-) in the presence of a proton source. These reactions proceed with varying degrees of success, and although primary amines generally afford the corresponding phosphinecarboxamides in good yields, secondary amines react more sluggishly and often give r...
متن کاملMagnetism in hafnium dioxide
Thin films of HfO2 produced by pulsed-laser deposition on sapphire, yttria-stabilized zirconia, or silicon substrates show ferromagnetic magnetization curves with little hysteresis and extrapolated Curie temperatures far in excess of 400 K. The moment does not scale with film thickness, but in terms of substrate area it is typically in the range 150–400 B nm −2. The magnetization exhibits a rem...
متن کاملHafnium germanium telluride
The title hafnium germanium telluride, HfGeTe(4), has been synthesized by the use of a halide flux and structurally characterized by X-ray diffraction. HfGeTe(4) is isostructural with stoichiometric ZrGeTe(4) and the Hf site in this compound is also fully occupied. The crystal structure of HfGeTe(4) adopts a two-dimensional layered structure, each layer being composed of two unique one-dimensio...
متن کاملOxidation of Hafnium and Diffusion of Hafnium Atoms in Hexagonal Close-Packed Hafnium; Microscopic Investigations by Perturbed Angular Correlations
Time-differential perturbed angular correlation (TDPAC) studies in hafnium metal (∼ 5%Zr) have been carried out at different temperatures. It is found that hafnium metal on heating at 873 K continuously for two days in air, transforms partially and abruptly to HfO2 while no component of oxide has been observed for heating up to 773 K and during initial heating at 873 K for 1 day. This result is...
