Nanoparticle research has progressed leaps and bounds mainly due to the unexpected properties exhibited by basic elements when their atomic and molecular properties are altered. Nanoparticles have made invaluable contribution to the field of pharmaceuticals, biomedicine, electronics and optics. This article will deal with the properties and applications of nickel zinc iron oxide nanoparticles.
Nickel zinc iron oxide (NiZnFe4O4) nanoparticles are available in carbon coated, high purity and dispersed forms. Nickel belongs to Block D, Period 4, zinc belongs to Block D, Period 4, iron belongs to Block D, Period 4 and oxygen belongs to Block P, Period 2 of the periodic table.
The chemical properties of nickel zinc iron oxide nanoparticles are given in the table below.

Zinc [Ar] 3d10 4s2
Oxygen [He] 2s2 2p4
Nickel zinc iron oxide nanoparticles appear in the form of a dark brown powder with a nearly spherical morphology. The table below lists the physical properties of these nanoparticles.
The thermal properties of nickel zinc iron oxide nanoparticles cannot be determined.
The following are the chief applications of nickel zinc iron oxide nanoparticles:
- Preparation of nickel cermet which is used as the anode layer of solid oxide fuel cells (SOFC)
- In lithium ion micro batteries as lithium nickel zinc iron cathode
- In plastics, textiles, electro chromic coatings
- In nanofiber, nanowire, alloys and catalyst applications.
