What is Tungsten Powder? Tungsten flour is used as a raw material to make tungsten powder, tungsten alloys, or tungsten products.
This metal has high hardness, low pressure and high density. Due to its dense structure, it has strong chemical properties that will not react with acid or alkali. Whilst tungsten is resistant to some bases and acids, it can also react with high-temperature oxidants and other molten materials. You can dissolve dense tungsten in aqua regia (100 110). Tungsten is widely used in special steels and chemical catalysts.

Tungsten powder uses
Tungsten is mainly used for the production of cemented caride and ferrotungsten. Tungsten is a heat-resistant and wear resistant alloy made from tungsten. It can be used as a refractory alloy with tantalum or niobium, and molybdenum. Tungsten-silver, and tungsten alloys are both used for making electrical contacts. For radiation protection, W-NiCu is a high-density alloy. Tungsten wires, rods, sheets, etc. They are used in the manufacture of parts for electric bulbs, electronic tubes, and electrodes forarc welding. Tin can also be used to make filters of various porosities from tungsten powder. FW-1 is used for the raw material of large slabs, tungsten rhenium galvanic couple and a few other purposes. FW-2 serves as a shielding material and contact alloy. FWP-1 is used in plasma spraying. The main raw material to process powder metallurgy of tungsten products is tungsten powder. You can make tungsten powder into wires, plates and rods. To make different tungsten alloys like W-Mo alloy, W.Re alloy, W.Cu alloy or high-density W, tungsten powder can also be combined with other metal powders. The tungsten-powder can also be used to produce tungsten carbide, which is then used to create cemented carbide tools like turning tools, milling cutters and drill bits.

Tungsten powder production method
You can make tungsten powder using many different methods. One of these is hydrogen reduction with tungsten dioxide. Two stages are required to produce tungsten, which is the classic hydrogen reduction process. The tungsten trioxide is obtained from roasting ammonium.tungstate. The traditional method of making tungsten powder can have many problems.
1. A low reduction temperature and a long time to react are some of the disadvantages.
2. It is used to reduce energy consumption. However, it is more complicated and difficult to operate.
3. This product is not very pure and is therefore difficult to manufacture continuously. The preparation procedure for tungsten-pulver powder CN201510177510 has a quick preparation time, and allows easy implementation of large-scale production. It is as follows:
(1) In distilled water, dissolve Na2WO4*5H2O and add CTAB.
(2) Add hydrochloric Acid Solution dropwise, and stir and mix evenly with magnetic force.
(3) Heating the solution by placing it in a hot-pressure reactor kettle.
(4) Cooling to room temp and filtering to get precipitate.
For tungsten trioxide powder, place the dry precipitate in a microwave oven.
Placing tungsten oxide powder into a plasma reaction chamber. Ionizing inert gases in the reaction chamber will form high-temperature Plasma. Heating the tungsten-trioxide-powder by high-temperature radiation to turn it into tungsten in an atmosphere reducing the temperature. To prepare tungsten dioxide, this process uses hydrochloric, CTAB, and sodium tungstate. Next, the plasma-arc method is used to produce tungsten powder. Due to the high temperature difference between the tungsten and the cooling medium, nucleation can be promoted. The growth of crystal nucleus in the prepared tungsten is also inhibited. This method offers the benefits of being simple, fast to prepare, and easy implementation of large-scale production.

Tungsten powder prices
Tungsten Powder particle sizes and purity can affect product prices. Also, the volume of the order may affect Tungsten Powder's cost. Large quantities of smaller amounts will result in a lower price. On our official website, you can see the price for Tungsten Powder.
