What Exactly is Spherical Tungsten Powder?
Spherical tungsten powder is a kind of tungsten which has been specifically made to print 3D. This powder is meticulously intended to constitute the model of a spherical that is why each powder particle being extremely homogeneous and small in proportions, permitting excellent printing results.
Precisely what is Tungsten Powder?
Tungsten powder is a form of powdered metallic tungsten, utilized as being a raw material for your preparation of tungsten-processed substances for example alloys, tungsten products and. It really is a gray-black metal with a metallic Lustre (body-centred cubic crystal). Melting point 3400. Boiling points 5555. The tungsten’s hardness is regarded as the hard of your metals. The toughest tungsten rod is 200250 and is particularly the toughest tungsten rod which has been spun right after the spinning hammer spins is 350400. It is actually soluble throughout the mix acid of nitric acid as well as hydrofluoric acid. It melts in the mix of sodium hydroxide and carbonate. A little soluble in nitric acid and sulfuric acid along with 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 really a solid cylindrical structure that may be body-centered. Type B tungsten will be able to be located in the presence of oxygen. It is stable to 630degC, after which transforms to your tungsten at temperatures above 630degC. This treatment is unreversible.
Difference between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder both are powder types 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 can be a spherical powder after special processing. This spherical shape allows tungsten powder to circulate 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 within the nanometer range. This fine particle size allows 3D printing tungsten to put better in to the nozzle in the 3D printer, providing finer print details. At the same time, the fine particles are also capable of fill paper bed, boosting the density and strength in the printed part.
Applications
Tungsten powder has a wide array of applications in several fields, such as bulb manufacturing, electronics, and mechanical parts. Over these applications, tungsten powder is frequently used as a filler or alloying element. Spherical tungsten powder, in the other hand, is particularly ideal for areas such as 3D printing, where it is capable of doing creating more complicated, high-precision parts and devices because of its excellent flowability, filling effect and printability.
How would you prepare tungsten powder?
It really is produced by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The process of making the tungsten powder through hydrogen reduction might be split up into two phases one stage within the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; within the second phase, at 700-900°C after which tungsten dioxide will likely be reduced to the tungsten powder. The reduction reaction is generally performed by the type of a tube or rotary furnace.
The efficiency of tungsten reduced powder (like quality in addition to particle size, composition, size, etc.) mostly depends inside the way of reduction. During this process of reducing tungsten in an oven tube, the key factors which affect the speed of reduction are temperatures of reduction, volume of tungsten oxide in the burner vessel as well as the speed of motion that this vessel is within, plus the rate of flow of hydrogen, and the quantity of moisture in hydrogen. Since the temperatures of reduction, scale of tungsten powder gets more coarse.
Creation of tungsten powder together with the way of hydrogen reduction, additionally there is a tungsten oxide carbon reduction methods employed at the beginning The reduction temperature is in excess of 1050 degrees Celsius . The purity from the tungsten oxide powder which is produced applying this technique is poor. Furthermore, with the use of 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 dimension is lower than .05mm.
Industrial production is possible with the decrease in tungsten trioxide by hydrogen, or ammonium partungstate is treated with acid then tungsten trioxide can be made by maturation decomposition after which reduced using hydrogen.
Hydrogen reduction using tungsten trioxide hydrogen reduction can be carried out in 2 steps The initial stage happens when tungsten trioxide heating to 550-800 , using hydrogen reduction. The following stage of reduction transpires between 650 and 850 the tungsten powder is completed.
Also, it is possible to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, or else by hydrogen then reduce it straight back to tungsten by hydrogen. The shape and content of your tungsten powder are a significant quality indicator of your tungsten powder. The reduction process is performed using a tube or even the rotary furnace.
Spherical tungsten powder offers the following advantages:
Spherical shape: The spherical shape allows the tungsten powder to improve fill the print bed during the printing process, providing a much more uniform print result. Compared with traditional granular tungsten powder, spherical tungsten powder can better adjust to the 3D printing head and provide a smoother printing process.
Fine particle size: The fine particle size allows the tungsten powder to better match the nozzle in the 3D printer, providing finer print details. The fine particles also fill paper bed better, increasing the density and strength from the printed part.
Uniform particle distribution: Uniform particle distribution reduces clogging and defects in the printing process and improves print success. In traditional granular tungsten powders, the particle distribution is generally not uniform enough, which can cause clogging or defects throughout the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this problem.
High purity: High-purity tungsten powder can offer better print performance and better print quality. In a few applications, it is actually required to use high-purity material for printing to be sure the quality and satisfaction of parts.
Spherical Tungsten Powder Application Areas

It needs to be noted that using spherical tungsten powder for 3D printing requires a certain level of skill and experience. In case you are a newbie, it is suggested to practice with some more accessible 3D printing materials first. At the same time, using tungsten powder for 3D printing also requires special focus to safety, as tungsten is really a high-density metal that will easily cause injury to a persons body. When you are performing so, make sure to follow the relevant safety regulations and operating procedures.
