Publisher:tungsten powder processing
The processing methods of tungsten powder include hydrogen reduction method and carbon reduction method, which are the early processing methods of tungsten powder. The principle is to use tungsten trioxide or ammonium paratungstate as raw material, and reduce tungsten oxide to tungsten powder in a reducing atmosphere. Of course, the tungsten oxide carbon reduction method is an early tungsten powder processing method, the reduction temperature is higher than 1050 ℃, and the purity of the obtained tungsten powder is low. New tungsten powder processing methods include high-energy ball milling method, gas evaporation method, plasma method, self-propagating high-temperature reduction method, molten salt electrolysis method, tungsten oxide powder reduction method, etc. These methods are all suitable for processing nano-metal tungsten powder. And show good development prospects.
The high-energy ball milling method uses the rotation or vibration of the ball mill to make the hard balls strongly impact, grind and stir the raw materials, which can significantly reduce the activation energy of the reaction, refine the grains, enhance the activity of the powder, improve the sintering ability, and induce low-temperature chemical reactions. A method of crushing metal or alloy powder into nano-sized particles.
The gas evaporation method is usually used for the dry production of nanopowders. The principle is the supersaturated concentration of metal vapor in the absence of refrigerant and carrier gas (such as argon, nitrogen) that acts as a crystal nucleation carrier.
The self-propagating high-temperature reduction method has become an extremely advantageous method for synthesizing and processing high-melting point materials (such as tungsten powder, etc.) due to its unique characteristics (short synthesis time, low energy consumption, high product purity, etc.). In the SHS process, tungsten oxide is used as the principle, and active metals are used as raw materials to synthesize tungsten powder through reduction.

As an important intermediate product of transition metal tungsten, tungsten powder has strong reducing properties and is often used to produce tungsten products such as tungsten oxide, tungstate, tungsten carbide, tungsten rods, and tungsten strips.
Tungsten alloy powder is an alloy composed of tungsten as the base and other elements. It is an alloy with tungsten powder as the main raw material and nickel, iron, copper and other elements as auxiliary materials.
For purchasers, there are many problems that need to be paid attention to when ordering ferro-tungsten powder. In fact, the requirements for tungsten iron powder are relatively high when it is used.
With the advancement of electronic information industry technology, products are increasingly miniaturized, and the performance requirements of materials are getting higher and higher, and ordinary materials can no longer meet the needs.
For tungsten powder manufacturers, the current situation is quite difficult, because the powder purchase orders of cemented carbide enterprises are often priced with reference to raw materials.
Tungsten carbide powder has high purity, uniform particle size and good dispersion. It is an important raw material for the production of cemented carbide.
Tungsten carbide particles are a kind of metal carbide powder and an alloy powder. Tungsten carbide is the main raw material for the manufacture of cemented carbide, and it is also an important raw material for the preparation of high wear-resistant coatings in the field of thermal spraying.
Metal surface processing is a very common way in the current industrial production; the reason why metal surface processing is done is to enhance its quality, such as tungsten carbide for spraying used in metal surface hardness reinforcement pink.
Tungsten powder production plants have a very important position in the current market. For many industrial manufacturers, they are important partners in purchasing tungsten powder.
