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 to 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 500700oC. In the second stage of the process, tungsten bioxide is reduced to powder at 700900oC. The reduction reaction takes place in either a tubular electric or rotary furnace. It is important to know the performance characteristics of the reduced powder tungsten (i.e., purity, composition and size). 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 temperature decreases, the tungsten powder's particle size becomes larger.
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 2-10 of the Fisher size m.m. 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 powder and their quality. 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 describes the properties and classification grades for tungsten powder. The standard specifies how to inspect, transport, and store it. 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 wires and tubes from pure tungsten powder. Mixed tungsten powder can make a number of different tungsten alloys. These include tungsten rhenium and tungsten molybdenum. The tungsten-powder can also be used in making tungsten carbide powder. This is useful for turning tools, drilling tools, and other tools that use cemented carbide such as milling cutters.
The price of tungsten dust
Price will depend on how finely tungsten powder is made. The purchase volume may also have an effect on price. Large quantities of small amounts will result in a lower price. On our official website, you can see the cost of tungsten powder.
