What is Spherical Tungsten Powder?
Spherical tungsten powder the type of tungsten that has been designed specifically to print 3D. This powder is meticulously designed to constitute the shape of a spherical for this reason each powder particle being extremely homogeneous and small in proportions, making it possible for excellent printing results.
What exactly is Tungsten Powder?
Tungsten powder is a kind of powdered metallic tungsten, utilized like a raw material for the preparation of tungsten-processed substances like alloys, tungsten products and. It is a gray-black metal by using a metallic Lustre (body-centred cubic crystal). Melting point 3400. Boiling points 5555. The tungsten’s hardness is the most hard of your metals. The most challenging tungsten rod is 200250 and it is the toughest tungsten rod that has been spun right after the spinning hammer spins is 350400. It is actually soluble within the mix acid of nitric acid in addition to hydrofluoric acid. It melts within the mixture 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 can be found in the presence of oxygen. It can be stable to 630degC, and after that transforms to your tungsten at temperatures above 630degC. This procedure is unreversible.
Distinction between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder are generally powder types of tungsten, however they have obvious variations in morphology, particle size and application.
Tungsten powder is usually in granular form, while spherical tungsten powder is really 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.
While tungsten powders have relatively large particle sizes, spherical tungsten powders have very fine particle sizes, usually inside the nanometer range. This fine particle size allows 3D printing tungsten to put better into the nozzle from the 3D printer, providing finer print details. Simultaneously, the fine particles will also be capable to fill paper bed, increasing the density and strength in the printed part.
Tungsten powder has a variety of applications in lots of fields, such as light manufacturing, electronics, and mechanical parts. Over these applications, tungsten powder is frequently used like a filler or alloying element. Spherical tungsten powder, on the other hand, is extremely suitable for areas such as 3D printing, where it can perform creating more complicated, high-precision parts and devices due to the 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 could be split up into two phases one stage within 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 be reduced towards the tungsten powder. The reduction reaction is usually performed by the form of a tube or rotary furnace.
The efficiency of tungsten reduced powder (such as quality along with particle size, composition, size, etc.) mostly depends in the means of reduction. In the process of reducing tungsten inside an oven tube, the key factors which affect the velocity of reduction are temperatures of reduction, level of tungsten oxide in the burner vessel as well as the speed of motion that the vessel is, as well as the rate of flow of hydrogen, and the amount of moisture in hydrogen. Because the temperatures of reduction, measurements of tungsten powder gets more coarse.
Manufacturing of tungsten powder together with the approach to 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 your tungsten oxide powder that is certainly produced by using this technique is poor. Furthermore, by using calcium, aluminum zinc, and various other reduction processes of tungsten oxide research is currently underway. For specific applications which require ultra-fine, ultrapure particle dimensions of tungsten powder the creation of the tungsten chloride hydrogen reduction process The tungsten powder particle dimension is lower than .05mm.
Industrial production may be accomplished through the decrease in tungsten trioxide by hydrogen, or ammonium partungstate is addressed with acid then tungsten trioxide can be produced by maturation decomposition after which reduced using hydrogen.
Hydrogen reduction using tungsten trioxide hydrogen reduction can be carried out by two steps The 1st 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 completed.
Also, it is possible to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then reduce it to tungsten by hydrogen. The size and content in the tungsten powder are a significant quality indicator of your tungsten powder. The reduction process is conducted 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 contrast to traditional granular tungsten powder, spherical tungsten powder can better conform to the 3D printing head and supply a smoother printing process.
Fine particle size: The fine particle size allows the tungsten powder to improve fit into the nozzle of the 3D printer, providing finer print details. The fine particles also fill the print bed better, improving 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 during the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this challenge.
High purity: High-purity tungsten powder can provide better print performance and higher print quality. In many applications, it is essential to use high-purity material for printing so that the quality and gratification of parts.
Spherical Tungsten Powder Application Areas
Spherical tungsten powder has an array of applications, including although not restricted to the subsequent areas:
Aerospace: Spherical tungsten powder could be used to manufacture high-performance parts including aircraft structural components and engine parts. Over these applications, our prime strength, high density and high purity characteristics of tungsten powder can provide better printing performance and quality.

It needs to be noted that using spherical tungsten powder for 3D printing takes a certain degree of skill and experience. When you are a newcomer, it is suggested to apply with some more accessible 3D printing materials first. Concurrently, using tungsten powder for 3D printing also requires special attention to safety, as tungsten can be a high-density metal that could easily cause problems for a persons body. When performing so, be sure you keep to the relevant safety regulations and operating procedures.
