What is Spherical Tungsten Powder?
Spherical tungsten powder the type of tungsten that has been specifically made to print 3D. This powder is meticulously made to constitute the form of a spherical for this reason each powder particle being extremely homogeneous and small in proportion, making it possible for excellent printing results.
What exactly is Tungsten Powder?
Tungsten powder is a kind of powdered metallic tungsten, utilized as a raw material for that preparation of tungsten-processed substances for example alloys, tungsten products and. It 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 from the metals. The toughest tungsten rod is 200250 in fact it is the most difficult tungsten rod that has been spun after the spinning hammer spins is 350400. It is actually soluble inside the mix acid of nitric acid in addition to hydrofluoric acid. It melts inside the combination of sodium hydroxide and carbonate. A bit 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 can be a solid cylindrical structure that is body-centered. Type B tungsten has the capacity to be found in the presence of oxygen. It really is stable to 630degC, and after that transforms into a tungsten at temperatures above 630degC. This procedure is unreversible.
Distinction between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder are both powder types of tungsten, however they have obvious differences in morphology, particle size and application.
Morphology
Tungsten powder is generally in granular form, while spherical tungsten powder is a spherical powder after special processing. This spherical shape allows tungsten powder to flow and fill better in applications including 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 3D printed tungsten to fit better in the nozzle in the 3D printer, providing finer print details. At the same time, the fine particles are also capable of fill the print bed, improving the density and strength of your printed part.
Applications
Tungsten powder has a wide array of applications in many fields, for example light manufacturing, electronics, and mechanical parts. In these applications, tungsten powder is usually used as being a filler or alloying element. Spherical tungsten powder, on the other hand, is especially suitable for areas like 3D printing, where it is capable of doing creating more technical, high-precision parts and devices because of its excellent flowability, filling effect and printability.
How can you prepare tungsten powder?
It is produced by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The whole process of making the tungsten powder through hydrogen reduction may be split into two phases one stage inside the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the second phase, at 700-900°C after which tungsten dioxide is going to be reduced for the tungsten powder. The reduction reaction is generally done by the sort of a tube or rotary furnace.
The efficiency of tungsten reduced powder (such as quality along with particle size, composition, size, etc.) mostly depends within the means of reduction. Along the way of reducing tungsten in an oven tube, the primary factors which affect the velocity of reduction are temperatures of reduction, level of tungsten oxide in to the burner vessel and the speed of motion how the vessel is within, and also 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.
Production of tungsten powder in addition to the approach to hydrogen reduction, there is also a tungsten oxide carbon reduction methods employed at the beginning The reduction temperature is higher than 1050 degrees Celsius . The purity of the tungsten oxide powder that is produced applying this strategy is poor. Furthermore, with the aid of calcium, aluminum zinc, as well as other reduction processes of tungsten oxide scientific studies are currently underway. For specific applications which require ultra-fine, ultrapure particle dimensions of tungsten powder the introduction of the tungsten chloride hydrogen reduction process The tungsten powder particle dimension is under .05mm.
Industrial production is possible with the reduction of tungsten trioxide by hydrogen, or ammonium partungstate is addressed with acid and then tungsten trioxide can be made by maturation decomposition and then reduced using hydrogen.
Hydrogen reduction using tungsten trioxide hydrogen reduction can be achieved in just two steps The first stage takes place when tungsten trioxide heating to 550-800 , using hydrogen reduction. Another stage of reduction takes place between 650 and 850 the tungsten powder is finished.
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 to tungsten by hydrogen. The size and content of the tungsten powder are an important quality indicator in the tungsten powder. The reduction process is conducted via a tube or the rotary furnace.
Spherical tungsten powder offers the following advantages:
Spherical shape: The spherical shape allows the tungsten powder to higher fill paper bed throughout the printing process, providing a far more uniform print result. In comparison with traditional granular tungsten powder, spherical tungsten powder can better adapt to the 3D printing head and provide a smoother printing process.
Fine particle size: The fine particle size allows the tungsten powder to improve fit into the nozzle in the 3D printer, providing finer print details. The fine particles also fill paper bed better, enhancing the density and strength of 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 often 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 issue.
High purity: High-purity tungsten powder offers better print performance and higher print quality. In some applications, it is actually essential to use high-purity material for printing so that the quality and performance of parts.

It must be noted that using spherical tungsten powder for 3D printing needs a certain degree of skill and experience. In case you are a novice, it is recommended to rehearse with some 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 may easily cause damage to the human body. When you are performing so, be sure you follow the relevant safety regulations and operating procedures.
