Introduction

The prospects for utilizing nanoparticles with diameters of <100 nm in various applications is being widely researched around the world today.

This article discusses the properties and applications of iron cobalt nanoparticles. Iron is a Block D, Period 4 element, while cobalt is a Block D, Period 4 element.

Iron cobalt nanoparticles appear in black powder form. They are known to possess high magnetic saturation values and high Curie temperatures. They are graded as an irritant, and can cause skin, eye, and respiratory irritations.

Chemical Properties

The chemical properties of iron cobalt nanoparticles are outlined in the following table.

Chemical Data
Chemical symbol Fe-Co
CAS No. -
Group Iron 8
Cobalt 9
Electronic configuration Iron [Ar] 3d6 4s2
Cobalt [Ar] 3d7 4s2

Manufacturing Process

Iron cobalt nanoparticles can be synthesized using the chemical reduction reaction method of salts aqua-solutions by hydrazine hydrate in alkaline medium.

The synthesized nanoparticles can be characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and SQUID-magnetometry techniques.

Applications

The key applications of iron cobalt nanoparticles are as follows:

  • In electro magnetic machines and micro-equipment as magnetic nanoparticles capable of killing cancer cells
  • For magnetic data storage and magnetic resonance imaging (MRI)
  • In coatings, plastics, nanowires, nanofibers, and textiles and in specific alloy and catalyst applications
  • As a starting material for further surface modifications such a dextrancoating, or formation of magnetic polymer microspheres
  • In preparing magnetic recording materials, catalysts, and pigments.
