What is Rounded Tungsten Powder?

3d printed tungsten is a kind of tungsten that has been specifically made to print 3D. That dust is meticulously created to form the form of a round that’s why each dust compound being extremely homogeneous and small in proportions, enabling exceptional printing results.

What’s tungsten dust?

Tungsten dust is an application of powdered metallic tungsten, employed as a raw product for the preparation of tungsten-processed elements such as for example alloys, tungsten items and. It is just a gray-black material with a metallic Lustre (body-centred cubic crystal). Melting stage 3400. Boiling details 5555. The tungsten’s hardness is probably the most difficult of the metals. The toughest tungsten pole is 200250 and it is the toughest tungsten pole that has been spun after the spinning hammer revolves is 350400. It is soluble within the combine acid of nitric acid along with hydrofluoric acid. It melts in the mixture of sodium 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 versions A and B. At typical temperature and atmospheric stress, type A is just a solid round structure that’s body-centered. Type B tungsten is able to be found in the presence of oxygen. It is secure to 630degC, and then changes to a tungsten at temperatures over 630degC. That technique is unreversible.

Big difference between tungsten dust and round tungsten dust

Tungsten dust and tungsten round dust are generally dust types of tungsten, but they’ve evident variations in morphology, compound size and application.


Tungsten dust is usually in granular variety, while round tungsten dust is just a round dust following particular processing. That round form enables tungsten dust to flow and fill better in applications such as for example 3D printing, providing more standard printing results.

Compound Measurement

While tungsten grains have somewhat large compound shapes, round tungsten grains have really fine compound shapes, often in the nanometer range. That fine compound size enables Circular Tungsten Dust to match better to the nozzle of the 3D printer, providing smaller print details. At once, the fine contaminants are also in a position to fill the print sleep, increasing the thickness and power of the produced part.


Tungsten dust features a wide variety of applications in many areas, such as for example light bulb production, electronics, and technical parts. In these applications, tungsten dust is usually used as a filler or alloying element. Circular tungsten dust, on one other hand, is specially ideal for parts such as for example 3D printing, wherever it is capable of making more technical, high-precision areas and products due to its exceptional flowability, filling effect and printability.

How do you prepare tungsten dust?

It is created by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The procedure of earning the tungsten dust through hydrogen reduction can be split into two stages one stage in the very first stage, at temperatures of 500-700degC, tungsten oxide is paid off to tungsten oxide; in the 2nd period, at 700-900°C where stage tungsten dioxide will undoubtedly be paid off to the tungsten powder. The reduction reaction is normally executed by the proper execution of a tube or circular furnace.

The efficiency of tungsten paid off dust (such as quality along with compound size, structure, size, etc.) generally depends in the method of reduction. Along the way of reducing tungsten in a stove tube, the principal facets that affect the charge of reduction are temperatures of reduction, quantity of tungsten oxide to the burner vessel and the speed of action that the vessel is in, along with the charge of flow of hydrogen, and the amount of moisture in hydrogen. While the temperatures of reduction, size of tungsten dust gets more coarse.

Generation of tungsten dust combined with method of hydrogen reduction, there’s also a tungsten oxide carbon reduction strategies used in the beginning The reduction temperature is higher than 1050 levels Celsius.The love of the tungsten oxide dust that’s produced like this is poor. Moreover, with the usage of calcium, aluminum zinc, and many other reduction operations of tungsten oxide research is underway. For specific applications that require ultra-fine, ultrapure compound size of tungsten dust the growth of the tungsten chloride hydrogen reduction process The tungsten dust compound size is less than 0.05mm.

Professional creation can be achieved through the reduction 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 off applying hydrogen.

Hydrogen reduction applying tungsten trioxide hydrogen reduction can be accomplished in two steps The first stage is when tungsten trioxide heating to 550-800 , applying hydrogen reduction. The following stage of reduction happens between 650 and 850 the tungsten dust 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 content of the tungsten dust are an essential quality indicator of the tungsten powder. The reduction process is completed via a tube or the circular furnace.

Circular tungsten dust has the next advantages:

Circular form: The round form enables the tungsten dust to raised fill the print sleep throughout the printing process, providing a more standard print result. In contrast to standard granular tungsten dust, round tungsten dust can better conform to the 3D printing head and offer a softer printing process.

Great compound size: The fine compound size enables the tungsten dust to raised match to the nozzle of the 3D printer, providing smaller print details. The fine contaminants also fill the print sleep better, increasing the thickness and power of the produced part.

Standard compound distribution: Standard compound distribution decreases clogging and defects throughout the printing process and improves print success. In standard granular tungsten grains, the compound distribution is usually perhaps not standard enough, which could result in clogging or defects throughout the printing process. The standard compound distribution of round tungsten dust can effectively resolve this problem.

High love: High-purity tungsten dust can provide better print efficiency and higher print quality. In a few applications, it is required to utilize high-purity product for printing to guarantee the quality and efficiency of parts.

Circular Tungsten Dust Application Parts

Circular tungsten dust features a wide variety of applications, including however, not limited by the next parts:

Aerospace: Circular tungsten dust can be used to produce high-performance areas such as for example airplane structural components and engine parts. In these applications, the high power, high thickness and high love faculties of tungsten dust can provide better printing efficiency and quality.

Automotive market: Circular tungsten is employed for the creation of areas for automobiles, including framework areas, engine components and other parts. The strong toughness and opposition to temperature of tungsten dust can enhance printing quality and performance.

Medical subject Circular tungsten can be used to create medical products like dental implants, precise instruments and others. The high biocompatibility along with the high power of tungsten dust could enhance print quality and printing performance.

Structure: Circular tungsten dust can be used to produce architectural designs and components. The high power and wear-resistant qualities of tungsten dust can provide better printing efficiency and quality.

Technology: Circular tungsten dust can be used to produce gadgets, such as for example semiconductor products, signal boards and so on. The high thermal and electrical conductivity of tungsten dust can provide better printing efficiency and quality.

It should be noted that applying round tungsten dust for 3D printing requires a specific level of talent and experience. If you should be a novice, it is advised to practice with even more available 3D printing materials first. At once, applying tungsten dust for 3D printing also involves particular awareness of safety, as tungsten is just a high-density material that can easily trigger harm to the individual body. When doing so, be sure to follow the relevant safety rules and functioning procedures.
