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. The true potential of the nanomaterials was further highlighted by 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. Feynman, in his talk, spoke about new possible ways to manipulate and control atoms and molecules of different elements. After a very long time, Professor Norio Taniguchi used the term nanotechnology for this new science. 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. 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 Nickel Micron Powder

Nickel micron powder is extracted from nickel that is a Block D, Group 4, and Period 4 element. Nickel micron powder consists of black and high surface area spherical particles. These particles are usually of 5 nm to 100 nm in size, with a surface area of 5 to 50 m2/g range. Nickel is a hard and ductile transition metal with lustrous metallic silver appearance. It has a slow rate of oxidation that makes it corrosion resistant. The nickel is a good conductor of heat and electricity. It also shows magnetic properties below 345°C. There are only four ferromagnetic elements, and nickel is one among them, and it is used to produce various types of magnets for commercial purposes. It is more commonly found in nature in the form of ores and is rarely available as a free element. Moreover, it has several other unique physical and chemical properties that are evident in the nickel micron powder as well.

Nickel micron powder form of the nickel inherent its properties from nickel, and it consists of black spherical high surface area particles. Pure nickel micron powder form is the development to maximize the reactive surface area and exhibits great chemical activities as compared to the bulk form.
