What Exactly is Spherical Tungsten Powder?
Spherical tungsten powder is a type of tungsten that has been created specifically to print 3D. This powder is meticulously intended to constitute the form of a spherical this is why each powder particle being extremely homogeneous and small in dimensions, making it possible for excellent printing results.
What is Tungsten Powder?
Tungsten powder is a type of powdered metallic tungsten, utilized like a raw material for your preparation of tungsten-processed substances such as alloys, tungsten products and. It is actually a gray-black metal by using a metallic Lustre (body-centred cubic crystal). Melting point 3400. Boiling points 5555. The tungsten’s hardness is regarded as the hard from the metals. The most challenging tungsten rod is 200250 in fact it is the most difficult tungsten rod that has been spun once the spinning hammer spins is 350400. It is soluble throughout the mix acid of nitric acid in addition to hydrofluoric acid. It melts in the combination of sodium hydroxide and carbonate. Just a little soluble in nitric acid and sulfuric acid in addition to aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two varieties A and B. At normal temperature and atmospheric pressure, type A is a solid cylindrical structure that is body-centered. Type B tungsten is able to be located in the presence of oxygen. It can be stable to 630degC, then transforms to a tungsten at temperatures above 630degC. This treatment is unreversible.
Distinction between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder are generally powder kinds of tungsten, nonetheless they have obvious differences in morphology, particle size and application.
Morphology
Tungsten powder is normally in granular form, while spherical tungsten powder is actually a spherical powder after special processing. This spherical shape allows tungsten powder to flow and fill better in applications like 3D printing, providing more uniform printing results.
Particle Size
While tungsten powders have relatively large particle sizes, spherical tungsten powders have very fine particle sizes, usually from the nanometer range. This fine particle size allows 200 mesh tungsten powder to match better into the nozzle of your 3D printer, providing finer print details. At the same time, the fine particles may also be capable to fill paper bed, increasing the density and strength from the printed part.
Applications
Tungsten powder has a wide array of applications in many fields, including light bulb manufacturing, electronics, and mechanical parts. Within these applications, tungsten powder is normally used as a filler or alloying element. Spherical tungsten powder, in the other hand, is specially ideal for areas such as 3D printing, where it is capable of creating more complicated, high-precision parts and devices because of its excellent flowability, filling effect and printability.
How do you prepare tungsten powder?
It is created by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The whole process of making the tungsten powder through hydrogen reduction can be divided into two phases one stage from the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; within the second phase, at 700-900°C at which point tungsten dioxide will likely be reduced to the tungsten powder. The reduction reaction is normally performed by the type of a tube or rotary furnace.
The efficiency of tungsten reduced powder (such as quality as well as particle size, composition, size, etc.) mostly depends in the way of reduction. At the same time of reducing tungsten in a oven tube, the main factors which affect the rate of reduction are temperatures of reduction, quantity of tungsten oxide to the burner vessel as well as the speed of motion that the vessel is at, and also the rate of flow of hydrogen, and the volume of moisture in hydrogen. As being the temperatures of reduction, measurements of tungsten powder gets more coarse.
Manufacture of tungsten powder along with the approach to hydrogen reduction, there is also a tungsten oxide carbon reduction methods employed at first The reduction temperature is higher than 1050 degrees Celsius . The purity of your tungsten oxide powder which is produced by using this way is poor. Furthermore, if you use calcium, aluminum zinc, as well as other reduction processes of tungsten oxide research is currently underway. For specific applications that require ultra-fine, ultrapure particle scale of tungsten powder the introduction of the tungsten chloride hydrogen reduction process The tungsten powder particle size is less than .05mm.
Industrial production can be achieved from the lowering of tungsten trioxide by hydrogen, or ammonium partungstate is cured with acid and after that tungsten trioxide can be done by maturation decomposition after which reduced using hydrogen.
Hydrogen reduction using tungsten trioxide hydrogen reduction can be achieved in two steps The 1st stage takes place when tungsten trioxide heating to 550-800 , using hydrogen reduction. Another stage of reduction occurs between 650 and 850 the tungsten powder is completed.
Also, it can be easy to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then reduce it returning to tungsten by hydrogen. The size and style and content in the tungsten powder are a vital quality indicator from the tungsten powder. The reduction process is carried out through a tube or even the rotary furnace.
Spherical tungsten powder offers the following advantages:
Spherical shape: The spherical shape allows the tungsten powder to higher fill the print bed in the printing process, providing a far more uniform print result. In comparison with traditional granular tungsten powder, spherical tungsten powder can better adjust to the 3D printing head and offer a smoother printing process.
Fine particle size: The fine particle size allows the tungsten powder to higher squeeze into the nozzle of your 3D printer, providing finer print details. The fine particles also fill the print bed better, enhancing the density and strength from the printed part.
Uniform particle distribution: Uniform particle distribution reduces clogging and defects during the printing process and improves print success. In traditional granular tungsten powders, the particle distribution is often not uniform enough, which can cause clogging or defects through the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this concern.
High purity: High-purity tungsten powder can offer better print performance and better print quality. In some applications, it can be essential to use high-purity material for printing to be sure the quality and gratifaction of parts.
Spherical Tungsten Powder Application Areas

It ought to be noted that using spherical tungsten powder for 3D printing requires a certain degree of skill and experience. When you are a novice, it is suggested to practice with a few more accessible 3D printing materials first. At the same time, using tungsten powder for 3D printing also requires special attention to safety, as tungsten can be a high-density metal that can easily cause injury to a persons body. When conducting so, make sure you stick to the relevant safety regulations and operating procedures.
