Introduction

Nanotechnology is the science, technology, and engineering that revolves around nanoscale particles of about 1 to 100 nanometers. It is the study of extremely tiny things and their potential applications. The study has found its uses across several other scientific fields such as material sciences, biology, chemistry, physics, and engineering.

A physicist Richard Feynman started a discussion entitled "There is plenty of room at the bottom" at a meeting of American Physical Society on December 29, 1959. After a very long time, Professor Norio Taniguchi used the term nanotechnology for this new science. Feynman, in his talk, spoke about new possible ways to manipulate and control atoms and molecules of different elements. During the 1980s, a scanning tunneling microscope paved the way for the scientists to see individual atoms and hence, at last, the nanotechnology started its never-ending journey. No one knew back then that it would cause great wonders one day.

Do you wonder how small nanoparticles are? It is too small beyond our imagination. Particles of 1 to 100nm are involved in nanotechnology, and 1 nm is a billionth of a meter. Now, can you imagine how small nanoparticles are and how these tiny materials are controlled for the service of mankind? Let's share another scale to help you resolve your curiosity. One inch has 25,400,000 nanometers.

Nanotechnology is currently the area of intensive research because of the advantages of nanomaterials in a wide variety of potential applications in the biomedical, electronic field, and optics. Nanomaterials are more important and useful than bulk materials. The reason is the remarkable change in physical and chemical properties as the bulk materials are converted into nanoparticles of extremely small sizes. That is the reason that nanoparticles are the new focus of the material sciences and technology. However, there is a lot to discover because those tiny particles have a huge number of mysteries waiting for the discovery. 

Nanotechnology has now impacted several fields such as medical, environmental applications, engineering, communication, materials sciences, computing, chemistry, biology, etc. Improved manufacturing processes, water purification, nanomedicines, large-scale infrastructure auto-fabrication, nutrition, better food production, energy systems, environmental protection are among the most prominent benefits of nanotechnology.

Iron micron powder is another miracle of the advancements in the field of nanotechnology. These fine particles of iron are extracted from the iron metal. Iron is among the most ubiquitous transition metal among all other transition metals. It is also the fourth most abundant element in the Earth's crust. It has now become the structural backbone of our modern infrastructure. It seems very ironic that how such an important element has been somewhat neglected so far as compared to its own oxides and other metals such as gold, platinum, cobalt, nickel, etc.

Iron micron powder's micro-particles have a large surface area that makes those nanoparticles highly reactive. They are most widely used in medical and laboratory applications. Extravagant research is also being conducted to use iron micron powder or nanoparticles to remediate industrial sites contaminated with chlorinated organic compounds. These nanoparticles also have the potential to treat several other forms of contamination, such as polychlorinated biphenyls, organochloride pesticides, and chlorinated organic solvents.

History

During prehistoric times, fine nanoparticles were once used by artisans by glassmakers and potters, including fine particles of metals. For example, the Lycurgus Cup in the British Museum and a piece of Roman Pottery near 400 after Christ is believed to contain nanosized gold. Gradually, the use of the nanoparticles and research on these materials accelerated. In 1857, Michael Faraday described for the very first time several properties of metallic nanoparticles, including optical properties. During the 1970s and 1980s, thorough studies were conducted on the nanotechnology to fully research and exploit the properties of the nanomaterials. The advancements in the field of nanotechnology are now touching the heights of brilliance. The nanoparticles and metallic micron powders are being extensively used across several industries and for research purposes.

Properties of Iron Micron Powder

Metallic micron powders and nanoparticles have fascinated researchers and scientists for more than a hundred years now. The ratio between the number of surface atoms and the number of massive atoms significantly enhances with the size reduction. That is the reason that nanoparticles exhibit unique physical, chemical, electrical, optical, mechanical, and magnetic properties. Because of these properties, they are now heavily being used in biomedical applications and engineering.

Iron, a Block D and Period 4 element are a strong, malleable, and ductile metal. Iron micron powder consists of tiny particles of iron metal. These are highly reactive materials even more reactive than the bulk material. That is the reason that puts limits on its use in inert environments. The iron micron powder also shares unique properties with all other nanomaterials.

Physical Properties of Iron Micron Powder

Iron micron powder consists of fine nanoparticles of iron. They are spherical high surface area metal nanoparticles with an average size of nanoscale. It consists of particles with typically 10-250 nanometers with surface area in the region of 30 to 50 m2/g. Iron micron powder is popular for showing facile surface modifications and have a tendency to attach with other nanostructures or nanoparticles with chemical interaction.

Chemical Properties of Iron Micron Powder

The chemical properties of the iron micron powder almost entirely depend on the high surface area to volume ratio. A very significant quantity of energy is out there in the nanoparticles as surface-free energy. That is the reason that iron micron powder is highly beneficial for a non-oxidizing environment. Its high reactivity is also able to break the carbon-carbon bond that is one of the strongest bonds. This property to separate two carbon atoms from each other is the most coveted property of the iron micron powder across several industries because the cleavage of carbon-carbon bonds is hugely important for several numbers of industrially crucial chemical transformation.

Magnetic Properties of Iron Micron Powder

Magnetic nanoparticles are used in varied applications across several industries, such as diagnostics and bio-imaging. Another hugely important aspect of the iron micron powder is the magnetic properties of the iron nanoparticles. This property has been widely researched in the last couple of decades. The reason behind such huge research is the number of applications that can exploit the magnetic properties of the iron micron powder. Applications in areas such as medical science, biology, and spintronic greatly utilize the magnetic properties of the iron. Iron micron powder also has the potential to exhibit a unique magnetism called superparamagnetism. It is one of the most important characteristics of the nanoparticles that are only present in iron particles.
