Abstract HAFNIUM is a commercially available refractory metal which has outstanding corrosion resistance, good mechanical properties, and is readily amenable to standard fabrication techniques. These characteristics, coupled with its high thermal-neutron cross section, high-temperature allotropic transformation, and excellent electrical ...

Auger parameter of hafnium in elemental hafnium and in hafnium oxide
Surface Science, 2004Abstract X-ray photoelectron spectroscopy has been used to determine the Auger parameters in elemental hafnium and in hafnium oxide (HfO2). The zirconium Lα line has been used as a source of excitation to study the 3d core levels of hafnium, the 1s core level of oxygen, and the X-ray excited MNN Auger region of hafnium and KVV Auger region of oxygen.

Oxygen Reduction on Hafnium/Hafnium Carbide Nanoparticles
ECS Meeting Abstracts, 2015Non-precious metal nanoparticles are attractive candidates for oxygen electrocatalytic reduction in electrochemical energy conversion devices, such as fuel cells and batteries. Here we report for the first time electrocatalytic activity of hafnium/hafnium carbide nanoparticles towards the oxygen reduction reaction (ORR).

Hafnium Germanate from a Hydrous Hafnium Germanium Oxide Gel
Inorganic Chemistry, 1998The gel chemistry of germanium is explored through the formation and composition of a hydrous metal oxide precursor gel used in the preparation of the HfGeO(4) and HfGeO(4):Ti X-ray phosphors. The enhanced solubility of hexagonal GeO(2) in dilute ammoniacal solutions is exploited to give a convenient and high-yield precipitation.
