What is Spherical Tungsten Dust?

3d printing Sphericaltungsten powder is a type of tungsten that has been created specifically to print 3D. That powder is meticulously produced to make the design of a circular that is why each powder particle being extremely homogeneous and small in dimensions, enabling exceptional printing results.

What is tungsten powder?

Tungsten powder is an application of powdered metallic tungsten, applied as a fresh substance for the preparation of tungsten-processed elements such as for example alloys, tungsten services and products and. It is a gray-black steel with a metallic Lustre (body-centred cubic crystal). Reduction level 3400. Boiling details 5555. The tungsten’s hardness is the absolute most hard of the metals. The hardest tungsten pole is 200250 and it is the hardest tungsten pole that has been spun after the spinning sort moves is 350400. It is soluble within the combine p of nitric p as well as hydrofluoric acid. It melts in the mix of salt hydroxide and carbonate. A little soluble in nitric p and sulfuric p as well as aqua regia, insoluble in hydrofluoric p and water. potassium hydroxide. Tungsten has two versions A and B. At typical temperature and atmospheric stress, form A is a strong round design that is body-centered. Form T tungsten is ready can be found in the current presence of oxygen. It is secure to 630degC, and then turns to a tungsten at conditions above 630degC. That process is unreversible.

Big difference between tungsten powder and circular tungsten powder

Tungsten powder and tungsten circular powder are both powder kinds of tungsten, but they have evident differences in morphology, particle size and application.


Tungsten powder is generally in granular variety, while circular tungsten powder is a circular powder following particular processing. That circular shape allows tungsten powder to flow and fill better in programs such as for example 3D printing, providing more standard printing results.

Particle Measurement

While tungsten grains have fairly large particle styles, circular tungsten grains have really fine particle styles, generally in the nanometer range. That fine particle size allows Spherical Tungsten Dust to fit better into the nozzle of the 3D printer, providing better print details. At the same time frame, the fine particles may also be able to fill the print sleep, increasing the occurrence and energy of the produced part.


Tungsten powder includes a wide selection of programs in lots of fields, such as for example lamp manufacturing, technology, and mechanical parts. In these programs, tungsten powder is frequently applied as a gel or alloying element. Spherical tungsten powder, on another give, is specially ideal for parts such as for example 3D printing, wherever it is capable of creating more complex, high-precision areas and units due to its exceptional flowability, stuffing impact and printability.

How do you prepare tungsten powder?

It is created by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The process of earning the tungsten powder through hydrogen decrease could be divided in to two phases one stage in the initial stage, at conditions of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the 2nd stage, at 700-900°C where level tungsten dioxide will be reduced to the tungsten powder. The decrease reaction is normally executed by the proper execution of a tube or rotary furnace.

The effectiveness of tungsten reduced powder (such as quality as well as particle size, arrangement, size, etc.) mostly depends in the strategy of reduction. In the process of lowering tungsten in an oven pipe, the principal facets that affect the rate of decrease are conditions of decrease, quantity of tungsten oxide into the burner vessel and the speed of motion that the vessel is in, as well as the rate of flow of hydrogen, and the total amount of water in hydrogen. Because the conditions of decrease, size of tungsten powder gets more coarse.

Manufacturing of tungsten powder combined with approach to hydrogen decrease, there is also a tungsten oxide carbon decrease methods used at first The decrease temperature is higher than 1050 degrees Celsius.The love of the tungsten oxide powder that is made that way is poor. More over, with the use of calcium, metal zinc, and several other decrease functions of tungsten oxide research is currently underway. For particular programs that want ultra-fine, ultrapure particle size of tungsten powder the growth of the tungsten chloride hydrogen decrease process The tungsten powder particle size is less than 0.05mm.

Professional production can be performed through the reduced total of tungsten trioxide by hydrogen, or ammonium partungstate is treated with p and then tungsten trioxide could be created by maturation decomposition and then reduced applying hydrogen.

Hydrogen decrease applying tungsten trioxide hydrogen decrease could be accomplished in two steps The very first stage is when tungsten trioxide heating to 550-800 , applying hydrogen reduction. The following stage of decrease occurs between 650 and 850 the tungsten powder is finished.

Also, it is probable to reduce ammonium paratungstate into orange tungsten oxide (blue tungsten) initially by hydrogen, or, or even by hydrogen then reduce it back to tungsten by hydrogen. The size and material of the tungsten powder are an important quality signal of the tungsten powder. The decrease process is completed by way of a pipe or the rotary furnace.

Spherical tungsten powder has these advantages:

Spherical shape: The circular shape allows the tungsten powder to better fill the print sleep throughout the printing process, providing an even more standard print result. Weighed against conventional granular tungsten powder, circular tungsten powder can better conform to the 3D printing head and provide a softer printing process.

Fine particle size: The fine particle size allows the tungsten powder to better match into the nozzle of the 3D printer, providing better print details. The fine particles also fill the print sleep better, increasing the occurrence and energy of the produced part.

Standard particle distribution: Standard particle distribution reduces blocking and problems throughout the printing process and improves print success. In conventional granular tungsten grains, the particle distribution is generally not standard enough, which can lead to blocking or problems throughout the printing process. The standard particle distribution of circular tungsten powder can successfully solve this problem.

Large love: High-purity tungsten powder provides better print efficiency and larger print quality. In a few programs, it is essential to use high-purity substance for printing to ensure the quality and efficiency of parts.

Automotive business: Spherical tungsten is employed for the production of areas for automobiles, including frame areas, engine parts and different parts. The powerful durability and opposition to temperature of tungsten powder may enhance printing quality and performance.

Medical subject Spherical tungsten can be used to produce medical units like dental implants, medical instruments and others. The large biocompatibility as well as the large energy of tungsten powder could enhance print quality and printing performance.

Architecture: Spherical tungsten powder can be used to produce architectural types and components. The large energy and wear-resistant properties of tungsten powder provides better printing efficiency and quality.

Electronics: Spherical tungsten powder can be used to produce gadgets, such as for example semiconductor units, enterprise boards and so on. The large thermal and electrical conductivity of tungsten powder provides better printing efficiency and quality.

It should be observed that applying circular tungsten powder for 3D printing requires a certain amount of ability and experience. If you are a starter, it is advised to rehearse with some more available 3D printing resources first. At the same time frame, applying tungsten powder for 3D printing also requires particular attention to protection, as tungsten is a high-density steel that could quickly cause injury to the individual body. When doing this, make sure to follow the relevant protection rules and functioning procedures.
