What’s tungsten powder?
Reduced with hydrogen in either a four tube muffle furnace (using tungsten dioxide as the raw material) or multi-tube furnace (using tungstenoxide). It has a particle size of 0.6-30 microns. It can be divided into medium, fine and coarse particles. It is determined using the national standard for impurity. The impurity content is determined by the national standard. Preparing tungsten powder using hydrogen reduction generally involves two stages. In the first, there is a reduction in tungsten trioxide into tungsten dioxide at 500 to 700oC. In the second stage, tungsten bioxide is reduced to powder at 700 to900oC. The reduction reaction takes place in either a rotary or tubular electric furnace. It is important to know the performance characteristics of the reduced powder tungsten (such as its purity, size and composition). It all depends on how the reduction is done. Tubular furnaces can reduce tungsten to a powder. The process parameters that determine the reduction rate include the temperature, amount of tungsten dioxide in the burned boat, burning boat speed, flow rate of hydrogen, and moisture in hydrogen. As the reduction temperature increases, the particle size becomes larger in tungsten.
Standard properties of tungsten-powder
The oxygen content in tungsten powder should not exceed a specified limit. There are also certain specifications regarding the impurity level. The common tungsten particle size is approximately 210 times that of the Fisher size m.m. Most tungsten particles are polygonal in shape. The specific surface area of the tungsten powder, its bulk density, and tap density also have varying ranges. These properties have a direct impact on the production of high-quality tungsten products and the quality of the tungsten powder metallurgy materials. Tungsten powder has three types: purity, size and uses. In the beginning, tungsten-reduced tungsten slurry was divided into three grades according the chemical purity. Japan established the JISH2116-1979 industrial standard for Tungsten Powder. France, Britain and many other countries have their own unified national standards. For tungsten powder manufactured in China, Technical Conditions for Hydrogen Reduction (GB3458-82) has been formulated. This standard specifies the properties of tungsten powder and their classification grades. The standard specifies inspection procedures, accept rules, packing, transport, and storage. You can request tungsten powder to be made according to your requirements.
Use of tungsten powder
Processing powder metallurgy items and tungsten alloys begins with tungsten powder. You can make your tungsten powder into wires, rods and tubes. Mixed tungsten powder can make a number of different tungsten alloys. These include tungsten molybdenum, tungsten-rhenium and high density tungsten. The tungsten-powder can also be used in making tungsten carbide powder. This is useful for turning tools, drilling tools and drills as well as milling cutters.
The price of tungsten dust
Price will depend on the quality and size of the tungsten powder particles. The purchase volume may also have an effect on how much tungsten powder is purchased. Large quantities of small amounts will result in a lower price. On our official website, you can see the cost of tungsten powder.
