What is Spherical Tungsten Powder?
Spherical tungsten powder is a type of tungsten which has been specifically made to print 3D. This powder is meticulously intended to form the model of a spherical this is why each powder particle being extremely homogeneous and small in proportions, enabling excellent printing results.
Exactly what is Tungsten Powder?
Tungsten powder is a form of powdered metallic tungsten, utilized being a raw material for your preparation of tungsten-processed substances for example alloys, tungsten products and. It is actually 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 in the metals. The hardest tungsten rod is 200250 and it is the most difficult tungsten rod which has been spun once the spinning hammer spins is 350400. It can be soluble throughout the mix acid of nitric acid in addition to hydrofluoric acid. It melts from the mix 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 can be in the presence of oxygen. It is stable to 630degC, and after that transforms to some tungsten at temperatures above 630degC. This process is unreversible.
Distinction between tungsten powder and spherical tungsten powder
Tungsten powder and tungsten spherical powder both are powder sorts of tungsten, but they have obvious variations in morphology, particle size and application.
Tungsten powder is generally 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 such as 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 Sphericaltungsten powder to fit better in the nozzle of the 3D printer, providing finer print details. Concurrently, the fine particles are also capable to fill paper bed, increasing the density and strength of the printed part.
Tungsten powder has an array of applications in many fields, like light manufacturing, electronics, and mechanical parts. Within these applications, tungsten powder is usually used being a filler or alloying element. Spherical tungsten powder, in the other hand, is particularly suitable for areas like 3D printing, where it can do creating more complex, high-precision parts and devices due to the excellent flowability, filling effect and printability.
How will you prepare tungsten powder?
It can be made by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The procedure of making the tungsten powder through hydrogen reduction could 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 after which tungsten dioxide will likely be reduced to the tungsten powder. The reduction reaction is typically done by the shape of a tube or rotary furnace.
The efficiency of tungsten reduced powder (including quality along with particle size, composition, size, etc.) mostly depends within the means of reduction. At the same time of reducing tungsten inside an oven tube, the main factors that affect the velocity of reduction are temperatures of reduction, amount of tungsten oxide to the burner vessel along with the speed of motion that the vessel is, as well as the rate of flow of hydrogen, and the level of moisture in hydrogen. Since the temperatures of reduction, scale of tungsten powder gets more coarse.
Production of tungsten powder together with the approach to hydrogen reduction, there is also a tungsten oxide carbon reduction methods employed in the beginning The reduction temperature is higher than 1050 degrees Celsius . The purity of your tungsten oxide powder that may be produced applying this strategy is poor. Furthermore, with the aid 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 size of tungsten powder the creation of the tungsten chloride hydrogen reduction process The tungsten powder particle dimensions are lower than .05mm.
Industrial production can be accomplished through the lowering of tungsten trioxide by hydrogen, or ammonium partungstate is treated with acid and then tungsten trioxide can be created by maturation decomposition after which 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 next stage of reduction happens between 650 and 850 the tungsten powder is completed.
Also, it is actually easy to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, or even by hydrogen then reduce it to tungsten by hydrogen. The dimensions and content of your tungsten powder are an essential quality indicator of the 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 better fill the print bed throughout the printing process, providing a far 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 improve match the nozzle from the 3D printer, providing finer print details. The fine particles also fill paper bed better, enhancing 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 generally not uniform enough, which can lead to clogging or defects in the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this challenge.
High purity: High-purity tungsten powder can offer better print performance and better print quality. In a few applications, it really is required to use high-purity material for printing to ensure the quality and gratification of parts.
Spherical Tungsten Powder Application Areas
Spherical tungsten powder has a wide range of applications, including yet not confined to the subsequent areas:
Aerospace: Spherical tungsten powder can be used to manufacture high-performance parts including aircraft structural components and engine parts. During these applications, our prime strength, high density and high purity characteristics of tungsten powder provides better printing performance and quality.

It needs to be noted that using spherical tungsten powder for 3D printing takes a certain measure of skill and experience. When you are a novice, it is strongly recommended to train with a few 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 will easily cause injury to a persons body. When performing so, be sure you stick to the relevant safety regulations and operating procedures.
