99.9% pure nickel is a high-purity, corrosion-resistant, and conductive metal used in specialized applications like battery research, electroplating, chemical processing, and electronics.

Available as foil, strip, or powder, this material offers excellent thermal and electrical properties, often used as substrates in chemical vapor deposition (CVD) or as high-grade components.

Nickel exhibits ferromagnetism and resists corrosion, properties that underpin its extensive industrial applications. The element occurs naturally in sulfide ores such as pentlandite and is extracted primarily through pyrometallurgical and hydrometallurgical processes.

First isolated as a distinct metal in 1751 by Swedish chemist Axel Fredrik Cronstedt from niccolite ore, nickel’s name derives from the German “Kupfernickel,” reflecting early miners’ frustration with its copper-like but non-yielding ore.

Today, over two-thirds of nickel production is alloyed into stainless and heat-resistant steels, with significant portions directed toward superalloys, electroplating, and, increasingly, lithium-ion batteries for electric vehicles, driving demand amid supply constraints from major producers like Indonesia.

Nickel has the chemical symbol Ni and atomic number 28, consisting of 28 protons in its nucleus. The ground-state electron configuration of neutral nickel atoms is 3d, 4s², with the 3d subshell featuring eight electrons distributed across five orbitals following Hund’s rule, resulting in two unpaired electrons that contribute to its paramagnetic properties.

In the metallic state, nickel atoms arrange in a face-centered cubic (FCC) lattice, characterized by the space group Fm¯3m and a lattice constant of 352.4 pm at room temperature.

This close-packed structure yields a coordination number of 12 for each atom and a packing efficiency of 74%, consistent with other FCC metals like copper. The metallic radius of nickel is 124.6 pm, reflecting the distance between nearest neighbors in the lattice divided by two.

Nickel’s atomic structure supports its role as a transition metal, with partially filled d-orbitals enabling variable oxidation states, primarily +2, and facilitating d-electron involvement in bonding and catalysis. The covalent radius is 115 pm, applicable in molecular compounds where nickel forms bonds via s and d orbitals.

Physical Characteristics:

Nickel is a hard, silvery-white transition metal with a lustrous appearance that resists tarnishing in air and can be polished to a high shine. It exhibits metallic luster and a slight golden tinge in pure form. The metal is malleable and ductile, allowing it to be drawn into wires or hammered into sheets.

At standard conditions, nickel has a density of 8.90 g/cm³ at 25°C. Its melting point is 1455°C and boiling point is 2913°C. Nickel possesses moderate thermal conductivity, approximately 90 W/(m·K), and electrical resistivity of about 7 × 10⁻⁸ Ω·m at room temperature, making it a fair conductor of heat and electricity.

Isotopes and Nuclear Properties:

Nickel possesses five stable isotopes that comprise essentially all naturally occurring nickel: ^{58}\mathrm{Ni}, ^{60}\mathrm{Ni}, ^{61}\mathrm{Ni}, ^{62}\mathrm{Ni}, and ^{64}\mathrm{Ni}. These isotopes have atomic masses ranging from 58 to 64 atomic mass units and exhibit nuclear stability characteristic of even-nucleon configurations, with ^{58}\mathrm{Ni} dominating due to its higher abundance.

Nickel is ferromagnetic at room temperature, with a Curie temperature around 358°C above which it becomes paramagnetic. In its solid state, nickel adopts a face-centered cubic crystal structure with a lattice parameter of approximately 352 pm at 20°C.
