The Wide Applications Of Magnetic Particles: Various Types And Uses
Nanoparticles to date have acquired a place in every industry. They are now an integral part of the production. Due to their variable properties and wide applications these particles are soon going to become the fundamental requirement of any industry.
There have been numerous nanoparticles such as silica, iron oxide, etc. But we are going to move a little further and talk about one another important particle that is widely being used; magnetic particles. These particles are a category of nanoparticles that are prepared using the magnetic field gradients and mostly consist of iron, nickel, etc. They have proved to be useful in industries and processes such as catalysis, data storage, magnetic part imaging, etc.
Types of Magnetic Particles and their Applications
Now talking about the types of these ferrous particles, these can broadly be classified into four categories, namely oxides, Ferrites, metallic and metallic with a shell. Amongst these, oxides have been studied deeply and certain properties have been found as a result of these studies. One of which is that these particles have a tendency to become superparamagnetic at a size less than 128 nm and hence exhibit their magnetic property only when the external field is applied.
These studies have also revealed that ferrites do not make strong covalent bonds, and magnetic particles possess higher magnetic moment. It is their properties that find an application in various industries, for example; oxides are well suited for biomedical practices whereas the ferrites have a technical application.
Now how are these particles with magnetic properties prepared? These particles exhibiting magnetic properties are prepared using the methods such as co-precipitation, thermal decomposition, micro-emulsion, flame spray synthesis, etc. They have acquired a strong place in the market and are now widely being used in the field of medicine, waste water treatment, information storage, genetic engineering, etc.
As the technology has progressed, you can get these particles delivered right to your doorstep. You just need to sit on the internet, choose the particle according to your requirements, and these particles will be sent across to you in no time.
