What’s Circular Tungsten Dust?

3d printed tungsten is a kind of tungsten that’s been created specifically to printing 3D. This powder is meticulously built to form the shape of a spherical that is why each powder chemical being exceedingly homogeneous and small in dimensions, allowing for exceptional printing results.

What is tungsten powder?

Tungsten powder is an application of powdered metallic tungsten, applied as a fresh product for the planning of tungsten-processed substances such as alloys, tungsten services and products and. It is a gray-black steel with a metallic Lustre (body-centred cubic crystal). Melting level 3400. Boiling items 5555. The tungsten’s hardness is the most difficult of the metals. The toughest tungsten rod is 200250 and it is the toughest tungsten rod that’s been spun following the spinning sort spins is 350400. It’s soluble within the mix acid of nitric acid along with hydrofluoric acid. It touches in the mix of salt 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 usual temperature and atmospheric pressure, form A is a strong cylindrical framework that is body-centered. Form N tungsten is able found in the presence of oxygen. It’s stable to 630degC, and then converts to a tungsten at temperatures above 630degC. This method is unreversible.

Big difference between tungsten powder and spherical tungsten powder

Tungsten powder and tungsten spherical powder are both powder forms of tungsten, but they’ve clear differences in morphology, chemical measurement and application.


Tungsten powder is normally in granular form, while spherical tungsten powder is a spherical powder after unique processing. This spherical form allows tungsten powder to flow and fill better in applications such as 3D printing, providing more uniform printing results.

Chemical Measurement

While tungsten powders have somewhat big chemical shapes, spherical tungsten powders have very great chemical shapes, frequently in the nanometer range. This great chemical measurement allows Spherical Tungsten Dust to suit better in to the nozzle of the 3D printer, providing greater printing details. At once, the great contaminants will also be able to fill the printing sleep, increasing the thickness and energy of the produced part.


Tungsten powder includes a wide variety of applications in several fields, such as bulb production, technology, and mechanical parts. In these applications, tungsten powder is usually used as a gel or alloying element. Spherical tungsten powder, on the other hand, is particularly suitable for parts such as 3D printing, where it is able of making more complicated, high-precision parts and devices due to its exceptional flowability, filling influence and printability.

How do you prepare tungsten powder?

It’s created by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The method of earning the tungsten powder through hydrogen decrease can be split into two phases one period in the first period, at temperatures of 500-700degC, tungsten oxide is paid down to tungsten oxide; in the second period, at 700-900°C at which level tungsten dioxide will soon be paid down to the tungsten powder. The decrease effect is usually executed by the shape of a pipe or circular furnace.

The efficiency of tungsten paid down powder (such as quality along with chemical measurement, structure, measurement, etc.) mostly depends in the strategy of reduction. In the process of lowering tungsten within an oven tube, the primary facets that influence the charge of decrease are temperatures of decrease, number of tungsten oxide in to the burner vessel and the speed of movement that the vessel is in, along with the charge of flow of hydrogen, and the amount of humidity in hydrogen. Because the temperatures of decrease, measurement of tungsten powder gets more coarse.

Generation of tungsten powder along with the approach to hydrogen decrease, there is also a tungsten oxide carbon decrease methods applied initially The decrease temperature is higher than 1050 levels Celsius.The purity of the tungsten oxide powder that is produced that way is poor. More over, with the usage of calcium, aluminum zinc, and some other decrease techniques of tungsten oxide research is underway. For specific applications that need ultra-fine, ultrapure chemical measurement of tungsten powder the progress of the tungsten chloride hydrogen decrease method The tungsten powder chemical measurement is less than 0.05mm.

Professional production can be achieved through the reduced total of tungsten trioxide by hydrogen, or ammonium partungstate is treated with acid and then tungsten trioxide can be created by maturation decomposition and then paid down applying hydrogen.

Hydrogen decrease applying tungsten trioxide hydrogen decrease can be accomplished in two measures The very first period is when tungsten trioxide heating to 550-800 , applying hydrogen reduction. The following period of decrease takes place between 650 and 850 the tungsten powder is finished.

Also, it is probable to lessen ammonium paratungstate in to orange tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then minimize it back to tungsten by hydrogen. The measurement and material of the tungsten powder are a significant quality indicator of the tungsten powder. The decrease method is completed through a tube or the circular furnace.

Spherical tungsten powder has these benefits:

Spherical form: The spherical form allows the tungsten powder to higher fill the printing sleep throughout the printing method, providing a more uniform printing result. Weighed against standard granular tungsten powder, spherical tungsten powder can better adapt to the 3D printing head and provide a smoother printing process.

Great chemical measurement: The great chemical measurement allows the tungsten powder to higher fit in to the nozzle of the 3D printer, providing greater printing details. The great contaminants also fill the printing sleep better, increasing the thickness and energy of the produced part.

Standard chemical circulation: Standard chemical circulation decreases blocking and defects throughout the printing method and increases printing success. In standard granular tungsten powders, the chemical circulation is normally not uniform enough, which can cause blocking or defects throughout the printing process. The uniform chemical circulation of spherical tungsten powder can efficiently resolve that problem.

Large purity: High-purity tungsten powder can provide better printing efficiency and higher printing quality. In some applications, it is necessary to utilize high-purity product for printing to guarantee the quality and efficiency of parts.

Spherical Tungsten Dust Software Places

Spherical tungsten powder includes a wide variety of applications, including but not limited by these parts:

Aerospace: Spherical tungsten powder can be utilized to production high-performance parts such as aircraft structural parts and engine parts. In these applications, the high energy, high thickness and high purity features of tungsten powder can provide better printing efficiency and quality.

Automotive market: Spherical tungsten is used for the production of parts for automobiles, including framework parts, engine parts and different parts. The powerful longevity and opposition to temperature of tungsten powder may enhance printing quality and performance.

Medical area Spherical tungsten can be utilized to create medical devices like dental implants, operative tools and others. The high biocompatibility along with the high energy of tungsten powder could enhance printing quality and printing performance.

Architecture: Spherical tungsten powder can be utilized to production architectural versions and components. The high energy and wear-resistant qualities of tungsten powder can provide better printing efficiency and quality.

Electronics: Spherical tungsten powder can be utilized to production gadgets, such as semiconductor devices, signal boards and therefore on. The high thermal and electrical conductivity of tungsten powder can provide better printing efficiency and quality.

It ought to be noted that applying spherical tungsten powder for 3D printing requires a particular level of ability and experience. If you should be a starter, it is preferred to practice with more available 3D printing products first. At once, applying tungsten powder for 3D printing also needs unique focus on safety, as tungsten is a high-density steel that can simply cause injury to the individual body. When this, make sure to follow the applicable safety rules and running procedures.
