Tungsten Nanoparticles Properties

What isTungsten Nanoparticles Nano W Powder?

Nanometer tungsten powder refers to the fine particles in tungsten powder at the nanometer level of powder. Nano-tungsten powder is prepared by nanotechnology. Tungsten has the highest melting point of any metal element. At its purest, tungsten surpasses the hardness of many sheets of steel. It is resistant to acids, bases, and oxygen.

Tungsten nanoparticles have a high specific surface area, which can reduce sintering temperature, low vapor pressure, abnormal quantum confinement, and grain boundary effect.

The nano-tungsten powder is a fine black powder composed of tungsten particles with diameters between 40 and 100 nanometers. It is used as a material in many fields, including microelectronics, metal processing, and chemical coatings. Tungsten, as a unique application of nanostructures in optics, electricity, and medicine, has become a material of high concern to researchers and engineers in various disciplines.

How are Tungsten Nanoparticles Nano W Powder Produced?

Tungsten nanoparticles were prepared by the acoustic electrochemical method using a platinum plate as an anode, titanium alloy horn connected to an ultrasonic generator as cathode, citric acid, ferrous sulfate, sodium tungstate, and trisodium citrate as electrolyte. The generation of ultrasonic promotes the electrochemical reaction and cavitation effect, thus forming Fe-W nanoparticles at the cathode. The iron atoms then dissolve in an acidic environment.


Applications of Tungsten Nanoparticles Nano W Powder :

Tungsten nanoparticle applications are as follows:

Products Coatings, Plastics, Nanowires, Nanofibers and Textiles; Microelectronics film; Gas sensor electrode; Sintering additive

Alloy for aerospace and electronic packaging, heat sinks, vacuum contactors, and vacuum load switches.

Coatings: Coatings produced using tungsten nanoparticles offer a variety of benefits unique to the material. Electrochromic coatings, cermet coatings, optical coatings, and other applications benefit from the use of tungsten nanoparticles. 

Thin films for microelectronic applications: Tungsten nanoparticles offer unique advantages for the production of thin films for microelectronic applications. The film's full potential has yet to be further studied, but the preliminary findings prove interesting.

Sintering Additives: Tungsten nanoparticles have shown extraordinary potential as sintering additives, and studies have shown that, with appropriate application, nano-powders will make traditional complex metallurgical processes easier.

Vacuum contactors and vacuum load switches: The unique properties of nanoscale tungsten make it an ideal material for vacuum contactors and vacuum load switches. There is still little research on tungsten's full potential in this regard, but the early signs are positive.


Storage Condition of Tungsten Nanoparticles Nano W Powder:

The damp reunion will affect tungsten nanoparticles' dispersion performance and use effects. Therefore, nano W powder should be sealed in vacuum packing and stored in a cool and dry room; the titanium nanoparticles can not be exposed to air. In addition, the W Nanoparticles should be avoided under stress.


Packing & Shipping of Tungsten Nanoparticles Nano W Powder:

We have many different kinds of packing, which depend on the tungsten nanoparticles quantity.

Tungsten nanoparticles packing: vacuum packing, 1kg/bag, 25kg/barrel, or as you request.

Tungsten nanoparticles shipping: could be shipped out by sea, by air, or by express as soon as possible once payment is received.
