Carbon Nanotubes

These modern manufactured materials are nanosized tubes made in small but bulk quantities. The diameter of each nanotube is only a few nm whilst the length can be several hundred nm.

The properties of nanotubes are very interesting in that the have differing conduction properties that range from metallic to superconducting depending on the configuration of the carbon atoms. But even more than that, the structural properties are also amazing, offering huge strength from so few atoms.

Carbon nanotubes are finding their way into a myriad of new products from tennis raquets to car bodies. Their use in tennis raquets comes from their lightness and at the sametime strength and in car bodies their conductive properties which better enable paint to be sprayed effectively on plastics.

However perhaps the most interesting uses is in the form of nano electronics and consumer electronics and perhaps ultimately may provide the backbone for a whole range of transistors leading to a new revolution in nano electronics.

Buying nanopowder

Nanopowder is available from a large range of suppliers, both traditional and more contemporary in a range of quantities from the tonne all the way down to micro grams. There are a range of companies and business specialities all keen to help you make the most of your purchase.

 

Market size for nanopowders

Nanomaterial consumption in market value is set to be around 13 billion and the nanopowder segment is the fastest growing and one of the largest segments of this industry. Nanopowder is expected to grow as a sector in its on right and go from strength to strength.

What is a nanopowder?

A nanopowder is a nanostructured material that conforms to the definition of being a powder. It may be a material made of a variety of constituents or it may be just one material.

A nanopowder could be a metal, a ceramic, or just about anything. The definition is that the grain size is typically sub 100 microns in diameter.

Nanopowders and nanomaterials are interesting because at the small scale, materials have fundamentally different properties than at the bulk due to increased surface area to volume ratios. Increased interaction and reactvity is one of the by products of materials that are nanoscale, which means potentially using less of the material or that even on the nanoscale the properties are so utterly different from that of the bulk scale.

There is much interest in nanopowders and they are findin their way into a variety of uses from drugs and processing to electronics. Its a seriously large industry with a growing market.

Nanopowder

In nanotechnology, a particle is defined as a small object that behaves as a whole unit in terms of its transport and properties. It is further classified according to size: in terms ofdiameter, fine particles cover a range between 100 and 2500 nanometers, while ultrafine particles, on the other hand, are sized between 1 and 100 nanometers. Similar to ultrafine particles, nanoparticles are sized between 1 and 100 nanometers. Nanoparticles may or may not exhibit size-related properties that differ significantly from those observed in fine particles or bulk materials. Although the size of most molecules would fit into the above outline, individual molecules are usually not referred to as nanoparticles.

Nanoclusters have at least one dimension between 1 and 10 nanometers and a narrow size distribution. Nanopowders are agglomerates of ultrafine particles, nanoparticles, or nanoclusters. Nanometer-sized single crystals, or single-domain ultrafine particles, are often referred to as nanocrystals. Nanoparticle research is currently an area of intense scientific interest due to a wide variety of potential applications in biomedical, optical and electronic fields.

powder is a dry, bulk solid composed of a large number of very fine particles that may flow freely when shaken or tilted. Powders are a special sub-class of granular materials, although the terms powder and granular are sometimes used to distinguish separate classes of material. In particular, powders refer to those granular materials that have the finer grain sizes, and that therefore have a greater tendency to form clumps when flowing. Granulars refers to the coarser granular materials that do not tend to form clumps except when wet.
