Diffusion of Nickel in Nickel Oxide
The Journal of Chemical Physics, 1957Diffusion coefficients for nickel in polycrystalline and monocrystalline nickel oxides have been measured by the surface-activity method from 1000 to 1400°C in air. Within experimental uncertainty the values D=4.4×10—4 exp(—44.2/RT) fit both cases. These results indicate that the oxidation of nickel under comparable conditions of T and P proceeds via ...

, 2012 Nickel (Ni) and chromium (Cr) are elements naturally present in all rock types and present in the pedosphere in a range from trace amounts to relatively high concentrations, as compared to other trace elements. Particularly high Ni and Cr concentrations are found in serpentine rocks and soils, originating from this rock type and colonized by a ...

Occupational Toxicology of Nickel and Nickel Compounds
Journal of Environmental Pathology, Toxicology and Oncology, 2009Nickel and nickel compounds are widely used in industry. The high consumption of nickel products inevitably leads to occupational and environmental pollution. In occupational settings, exposure to nickel and nickel compounds occurs primarily during nickel refining, electroplating, and welding.

The solubility of nickel in nickel ferrite
Journal of Physics and Chemistry of Solids, 1961Abstract A method is described for preparing high resistivity nickel ferrites with nickel excess. High resistivity materials can be made by suppressing Fe ++ and Ni +++ ions in the spinel lattice by suitable heat treatment. Electrical measurements indicate that excess nickel dissolves in the ferrite lattice up to a nickel to iron ratio of 1.029: 2.

Journal of the Chemical Society, Faraday Transactions 1: Physical Chemistry in Condensed Phases, 1974
Decomposition of nickel formate, nickel malonate, nickel maleate and nickel fumarate in oxygen yields nickel oxide and carbon dioxide only. The shape of each fractional reaction-time curve is comparable with that for the vacuum pyrolysis of the salt, there is no evidence that the product oxide provided a progressively increasing barrier to the progress
