Nanoparticles research is growing widely as they can be easily altered by changing their shape, size and chemical properties. Nanoparticles have unexpected optical properties, and produce quantum effects.
Nickel is more commonly found in ores and sometimes found free in nature. It can be alloyed with tungsten, molybdenum, chromium, iron and other metals to form corrosion-resistant alloys. It is electrically conductive and hence used for several applications. Nickel nanoparticles are available as nanofluid and in passivated, ultra high purity, high purity, coated and dispersed forms.
The chemical properties of nickel nanoparticles are outlined in the following table.

The physical properties of nickel nanoparticles are given in the following table.
The thermal properties of nickel nanoparticles are provided in the table below.
Nickel nanoparticles can be prepared from the thermal decomposition of nickel(II) acetylacetonate in alkylamines and characterized by transmission electron microscopy, magnetic measurement and powder x-ray diffraction.
The key applications of nickel nanoparticles are listed below:
- Anode of solid oxide fuel cells or conductive electrolytic layer of proton exchange membrane fuel cells
- Automotive catalytic converters
- Coatings, plastics, nanowires, nanofibers and textiles
- Magnetic fluid and catalyst
- Propellant and sintering additive.
