Although nickel is an essential element for animal nutrition, the physiological role of nickel is not yet established. Pathological alterations of nickel metabolism are recognized in several human diseases. The diverse clinical manifestations of nickel toxicology include: (1) acute pneumonitis from inhalation of nickel carbonyl, (2) chronic rhinitis and sinusitis from inhalation of nickel aeros...

Key Points Fire  Elemental nickel dust and nickel carbonyl are flammable  Nickel is incompatible with acids, oxidizing agents and sulphur  Nickel and nickel carbonyl react violently with oxidants  Nickel and nickel compounds emit toxic fumes and vapours of nickel carbonyl when heated to decomposition  In the event of a fire involving nickel carbonyl, use fine water spray and gas tight kit ...

Abstract The density of liquid iron-nickel-sulfur (Fe46.5Ni28.5S25) alloy was determined at pressures up to 74 GPa and an average temperature 3400 K via pair distribution function (PDF) analysis synchrotron X-ray diffraction (XRD) data obtained using laser-heated diamond-anvil cells. Fe46.5Ni28.5S25 is 8.03(35) g/cm3, 15% lower than that pure Fe. were fitted a third-order Vinet equation state (...
