What is Spherical Tungsten Powder?
Spherical tungsten powder is a form of tungsten which has been specifically made to print 3D. This powder is meticulously created to constitute the shape of a spherical this is why each powder particle being extremely homogeneous and small in proportion, enabling excellent printing results.
What is Tungsten Powder?
Tungsten powder is a form of powdered metallic tungsten, utilized as a raw material for that preparation of tungsten-processed substances such as alloys, tungsten products and. It really is a gray-black metal having 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 hardest tungsten rod is 200250 and is particularly the most challenging tungsten rod that has been spun after the spinning hammer spins is 350400. It is actually soluble inside the mix acid of nitric acid along with hydrofluoric acid. It melts from the blend of sodium hydroxide and carbonate. Just a little soluble in nitric acid and sulfuric acid and also 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 actually a solid cylindrical structure that is certainly body-centered. Type B tungsten has the capacity to be located in the presence of oxygen. It really is stable to 630degC, then transforms to some tungsten at temperatures above 630degC. This process is unreversible.
Difference between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder both are powder sorts of tungsten, nevertheless they have obvious differences in morphology, particle size and application.
Morphology
Tungsten powder is usually in granular form, while spherical tungsten powder is a spherical powder after special processing. This spherical shape allows tungsten powder to circulate and fill better in applications for example 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 in the nanometer range. This fine particle size allows 200 mesh tungsten powder to put better to the nozzle of your 3D printer, providing finer print details. At the same time, the fine particles can also be capable of fill the print bed, boosting the density and strength of the printed part.
Applications
Tungsten powder has an array of applications in several fields, such as light bulb manufacturing, electronics, and mechanical parts. Within these applications, tungsten powder is normally used being a filler or alloying element. Spherical tungsten powder, about the other hand, is specially suitable for areas such as 3D printing, where it is capable of creating more advanced, high-precision parts and devices for its excellent flowability, filling effect and printability.
How can you prepare tungsten powder?
It can be made by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The whole process of making the tungsten powder through hydrogen reduction may be split up into two phases one stage from the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the second phase, at 700-900°C at which point tungsten dioxide will probably be reduced towards the tungsten powder. The reduction reaction is generally performed by the form 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 principal factors which affect the pace of reduction are temperatures of reduction, level of tungsten oxide into the burner vessel along with the speed of motion the vessel is in, as well as the rate of flow of hydrogen, and the volume of moisture in hydrogen. As the temperatures of reduction, size of tungsten powder gets more coarse.
Creation of tungsten powder together with the means of hydrogen reduction, additionally there is a tungsten oxide carbon reduction methods employed initially The reduction temperature is greater than 1050 degrees Celsius . The purity of the tungsten oxide powder which is produced using this way is poor. Furthermore, by using calcium, aluminum zinc, as well as other reduction processes of tungsten oxide research is currently underway. For specific applications that need ultra-fine, ultrapure particle size of tungsten powder the creation of the tungsten chloride hydrogen reduction process The tungsten powder particle dimensions are less than .05mm.
Industrial production is possible with the lowering of tungsten trioxide by hydrogen, or ammonium partungstate is cured with acid and then tungsten trioxide can be created by maturation decomposition then reduced using hydrogen.
Hydrogen reduction using tungsten trioxide hydrogen reduction can be achieved in two steps The first stage happens when tungsten trioxide heating to 550-800 , using hydrogen reduction. The subsequent stage of reduction happens between 650 and 850 the tungsten powder is completed.
Also, it is actually possible to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then reduce it back to tungsten by hydrogen. The shape and content of your tungsten powder are an important quality indicator of your tungsten powder. The reduction process is conducted by way of a tube or maybe the rotary furnace.
Spherical tungsten powder provides the following advantages:
Spherical shape: The spherical shape allows the tungsten powder to higher fill paper bed through the printing process, providing a much more uniform print result. In comparison with traditional granular tungsten powder, spherical tungsten powder can better get accustomed to the 3D printing head and give a smoother printing process.
Fine particle size: The fine particle size allows the tungsten powder to higher go with the nozzle of your 3D printer, providing finer print details. The fine particles also fill the print bed better, increasing the density and strength from the printed part.
Uniform particle distribution: Uniform particle distribution reduces clogging and defects throughout the printing process and improves print success. In traditional granular tungsten powders, the particle distribution is normally not uniform enough, which can lead to clogging or defects throughout the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this concern.
High purity: High-purity tungsten powder offers better print performance and higher print quality. In some applications, it can be necessary to use high-purity material for printing so that the quality and performance of parts.
Spherical Tungsten Powder Application Areas

It ought to be noted that using spherical tungsten powder for 3D printing takes a certain amount of skill and experience. Should you be a newbie, it is strongly recommended to rehearse with many more accessible 3D printing materials first. As well, using tungsten powder for 3D printing also requires special focus to safety, as tungsten is actually a high-density metal that can easily cause harm to a persons body. When conducting so, make sure to stick to the relevant safety regulations and operating procedures.
