Sphericaltungsten powder is a type of tungsten that has been made especially to printing 3D. This dust is meticulously made to really make the kind of a curved this is exactly why each dust chemical being exceedingly homogeneous and small in proportions, allowing for outstanding printing results.

What’s tungsten dust?

Tungsten dust is an application of powdered metallic tungsten, used as a new product for the planning of tungsten-processed ingredients such as for example for example alloys, tungsten items and. It is a gray-black material with a metallic Lustre (body-centred cubic crystal). Melting period 3400. Boiling factors 5555. The tungsten’s hardness is the absolute most hard of the metals. The hardest tungsten post is 200250 and it’s the hardest tungsten post that has been spun after the turning sort moves is 350400. It’s soluble within the mix acid of nitric acid in addition to hydrofluoric acid. It variations in the mix of sodium hydroxide and carbonate. Only a little soluble in nitric acid and sulfuric acid in addition to aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two types A and B. At normal temperature and atmospheric pressure, type A is a stable circular design that is body-centered. Sort B tungsten is able are available in the presence of oxygen. It’s secure to 630degC, and then changes to a tungsten at situations around 630degC. This process is unreversible.

Difference between tungsten dust and curved tungsten dust

Tungsten dust and tungsten curved dust are generally dust kinds of tungsten, but they’ve distinct variations in morphology, chemical size and application.


Tungsten dust is typically in granular selection, while curved tungsten dust is a curved dust subsequent unique processing. This curved shape permits tungsten dust to movement and fill greater in applications such as for example for example 3D printing, providing more standard printing results.

Compound Size

While tungsten cereals have somewhat major chemical shapes, curved tungsten cereals have really fine chemical shapes, typically in the nanometer range. This fine chemical size permits Circular Tungsten Powder to fit greater in to the nozzle of the 3D printer, providing greater printing details. At the same time, the fine particles may also be ready to fill the printing sleep, increasing the occurrence and strength of the produced part.


Tungsten dust includes a wide selection of applications in lots of fields, such as for example for example lamp manufacturing, engineering, and bodily parts. In these applications, tungsten dust is often applied as a product or alloying element. Circular tungsten dust, on another hand, is extremely perfect for places such as for example for example 3D printing, wherever it’s ready of fabricating more difficult, high-precision areas and items because outstanding flowability, stuffing influence and printability.

How will you make tungsten dust?

It’s created by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The task of creating the tungsten dust through hydrogen decrease could possibly be divided into two stages one time in the original stage, at situations of 500-700degC, tungsten oxide is decreased to tungsten oxide; in the next stage, at 700-900°D that period tungsten dioxide will undoubtedly be decreased to the tungsten powder. The decrease influence is usually done by the appropriate execution of a tube or circular furnace.

The potency of tungsten decreased dust (such as quality in addition to chemical size, arrangement, size, etc.) mainly depends in the means of reduction. In the behave of reducing tungsten within an range pipe, the principal factors that effect the charge of decrease are situations of decrease, degree of tungsten oxide in to the burner vessel and the pace of activity that the vessel is in, in addition to the charge of movement of hydrogen, and the quantity of water in hydrogen. Since the situations of decrease, size of tungsten dust gets more coarse.

Production of tungsten dust combined with method of hydrogen decrease, there is also a tungsten oxide carbon decrease techniques used initially The decrease temperature is more than 1050 levels Celsius.The love of the tungsten oxide dust that is made this way is poor. Moreover, with the usage of calcium, metal zinc, and some other decrease operates of tungsten oxide research is underway. For particular applications that want ultra-fine, ultrapure chemical size of tungsten dust the development of the tungsten chloride hydrogen decrease process The tungsten dust chemical size is less than 0.05mm.

Commercial manufacturing may be achieved through the reduction of tungsten trioxide by hydrogen, or ammonium partungstate is handled with acid and then tungsten trioxide could possibly be created by maturation decomposition and then decreased applying hydrogen.

Hydrogen decrease applying tungsten trioxide hydrogen decrease could possibly be accomplished in two procedures The very first stage is when tungsten trioxide heat to 550-800 , applying hydrogen reduction. The following stage of decrease happens between 650 and 850 the tungsten dust is finished.

Also, it’s possible to reduce ammonium paratungstate in to blue tungsten oxide (blue tungsten) actually by hydrogen, or, if not by hydrogen then reduce it back to tungsten by hydrogen. The size and product of the tungsten dust are a significant quality sign of the tungsten powder. The decrease process is finished via a pipe or the circular furnace.

Circular tungsten dust has the next benefits:

Circular shape: The curved shape permits the tungsten dust to raised fill the printing sleep through the printing process, providing a more standard printing result. Considered against standard granular tungsten dust, curved tungsten dust may greater conform to the 3D printing mind and provide an easier printing process.

Great chemical size: The fine chemical size permits the tungsten dust to raised fit in to the nozzle of the 3D printer, providing greater printing details. The fine particles also fill the printing sleep greater, increasing the occurrence and strength of the produced part.

Standard chemical circulation: Standard chemical circulation reduces blocking and weaknesses through the printing process and increases printing success. In standard granular tungsten cereals, the chemical circulation is typically perhaps not standard enough, which may result in blocking or weaknesses through the printing process. The standard chemical circulation of curved tungsten dust may simply handle this problem.

Large love: High-purity tungsten dust can offer greater printing efficiency and larger printing quality. In a few applications, it is needed to employ high-purity product for printing to ensure the quality and efficiency of parts.

Circular Tungsten Powder Plan Places

Circular tungsten dust includes a wide selection of applications, including although not limited to the next places:

Aerospace: Circular tungsten dust works extremely well to produce high-performance areas such as for example for example plane architectural components and motor parts. In these applications, the large strength, large occurrence and large love options that come with tungsten dust can offer greater printing efficiency and quality.

Automotive business: Circular tungsten is helpful for the manufacturing of areas for automobiles, including body areas, motor components and different parts. The stable durability and opposition to temperature of tungsten dust may increase printing quality and performance.

Medical matter Circular tungsten works extremely well to make medical items like dental implants, medical products and others. The large biocompatibility in addition to the large strength of tungsten dust can increase printing quality and printing performance.

Structure: Circular tungsten dust works extremely well to produce architectural types and components. The large strength and wear-resistant houses of tungsten dust can offer greater printing efficiency and quality.

Technology: Circular tungsten dust works extremely well to produce electronics, such as for example for example semiconductor items, circuit panels and therefore on. The large thermal and electrical conductivity of tungsten dust can offer greater printing efficiency and quality.

It should be seen that applying curved tungsten dust for 3D printing requires a particular degree of skill and experience. If you are a novice, it’s chosen to apply with more accessible 3D printing products first. At the same time, applying tungsten dust for 3D printing also requires unique awareness of safety, as tungsten is a high-density material that’ll simply trigger damage to the in-patient body. When this, make sure to follow the appropriate safety rules and operating procedures.
