About Tungsten Nanoparticles Nano W Powder  :

Physical properties:

The physical properties of nano-tungsten are mainly affected by its particle size and shape. Because nano-tungsten size is smaller than traditional tungsten, its specific surface area increases, increasing surface energy. This gives nano tungsten better thermal stability and creep resistance at high temperatures. In addition, the lattice constants and elastic modulus of nano-tungsten also show different properties from conventional tungsten. For example, the lattice constant and elastic modulus of nano-tungsten increase with the decrease of particle size.

Chemical properties:

The chemical properties of nano-tungsten also differ from those of conventionally sized tungsten. Due to the large specific surface area and high surface energy of nano tungsten, its chemical activity increases. In the oxidizing environment, nano-tungsten shows higher oxidation resistance because the oxide layer it forms on the surface can effectively prevent further oxidation. In addition, nano-tungsten shows higher catalytic activity in some chemical reactions, which makes it have potential application value in the catalyst field.

Mechanical properties:

The mechanical properties of nano-tungsten have also changed. Due to the high specific surface area and vigorous surface activity of nano-tungsten, its hardness, toughness and wear resistance have been improved. In addition, the elastic modulus of nano-tungsten also shows different properties from conventional tungsten. For example, the elastic modulus of nano-tungsten increases as the particle size decreases. These properties make nano tungsten a potential high-performance material that can manufacture parts with high strength, wear resistance and high corrosion resistance.

Electrical properties:

The electrical properties of nano-tungsten have also changed. Due to the large specific surface area and high surface activity, nano-tungsten's conductivity, thermal conductivity and electron mobility are improved. These properties make nano tungsten have potential applications in the field of electronic devices, such as the manufacture of high-performance and high-sensitivity electronic devices.

Optical properties:

The optical properties of nano-tungsten have also changed. Due to the small size and high surface activity of nano-tungsten, its light absorption, scattering and reflection properties have changed. These properties make nano tungsten potentially valuable for optical devices, such as high-performance optical devices.

Production Method of Tungsten Nanoparticles Nano W Powder：

Physical law:

Physical methods usually include mechanical crushing and gas evaporation. Mechanical pulverization uses force to crush large-sized tungsten particles into nano-sized tungsten powder. The advantage of this method is that the production process is simple, but the disadvantage is low production efficiency. It isn't easy to obtain uniform nano tungsten powder. The gas evaporation method is to heat tungsten wire or tungsten rod so that it melts and evaporates into nano-sized tungsten particles. The advantage of this method is that high-purity nano tungsten powder can be obtained, but the disadvantage is that the production cost is high, and it is difficult to control the particle size and shape.

Chemical method:

The chemical method is a commonly used method to prepare nanomaterials, including the solution, gas, and solid phase methods. The solution method is one of the most widely used for producing nano-tungsten. In this method, tungsten salt solution is mixed with reducing agents (such as NaH, NH3, etc.), and the reduction reaction is carried out under specific temperature and pressure conditions to generate nano-sized tungsten particles. Gas-phase and solid-phase methods are also commonly used to produce nano-tungsten, but they usually require high temperatures and high-pressure situations, so the production cost is higher.

Physical and chemical method:

Physical chemistry is a method that combines the advantages of physical and chemical processes. It usually includes the sol-gel method, chemical vapor deposition method, etc. The sol-gel method is a standard method for the production of nano-tungsten. The technique is to dissolve tungsten compounds in organic solvents, add reducing agents (such as NaH, NH3, etc.), and conduct a reduction reaction under specific temperature and pressure conditions to generate nano-sized tungsten particles. Chemical vapor deposition is also a commonly used method, which is to mix tungsten compound vapor with hydrogen at high temperatures and conduct a reduction reaction under specific pressure conditions to generate nano-sized tungsten particles.
