Nano Tungsten Powder

Nano tungsten powder is fine particles of tungsten powder to the nano-level powder. The preparation of nano tungsten powder uses the nanotechnology.

What is the nanotechnology? Nanotechnology actually is the technology for a single atomic, molecular manufacturing.

There are three concepts about nanotechnology: The first is an American scientist Dr. Drexler pointed out the molecular nanotechnology in 1986. Under this concept, the combination molecules machines for practical use, and thus can combine all kinds of molecules,  and can turn out any kind of the molecular structure. This concept of nanotechnology does not make ​​significant progresses.

The second concept of nanotechnology is positioned as the limit of the micro-machining technology. That is, the "processing" of nanometer precision to manually form the structure of the technical of the nano-size. Even if the existing technology continues developing, it will eventually reach the limit. This is because, if the line width of the circuit is smaller, the enable circuit is constituted of an insulating film is extremely thin, so that  can destruct the insulation effect. In addition, there are issues such as fever and shaking. In order to solve these problems, researchers are studying a new type of nanotechnology.

A third concept is from the biological point of view. Originally, there nanoscale structure in biological cells and biofilms.
 

The nanotechnology, is to study the law of motion of electrons, atoms and molecules and characteristics of a new technology in a scale of 0.1 to 100 nm. Scientists find dozens of the number of atoms or molecules in the process of studying the material constitutions. Taking advantage of these features of manufacturing technology to make specific function devices ,this technology is known as nanotechnology.
