What is Spherical Tungsten Dust?

Sphericaltungsten powder is a type of tungsten that has been specifically designed to print 3D. This dust is meticulously created to create the form of a spherical that is why each dust particle being exceptionally homogeneous and small in dimensions, permitting exceptional printing results.


What is tungsten dust?

Tungsten dust is an application of powdered metallic tungsten, utilized as a raw product for the preparation of tungsten-processed substances such as alloys, tungsten products and. It is just a gray-black steel with a metallic Lustre (body-centred cubic crystal). Reduction level 3400. Boiling factors 5555. The tungsten’s hardness is the most difficult of the metals. The toughest tungsten pole is 200250 and it is the toughest tungsten pole that has been spun following the spinning sort revolves is 350400. It’s soluble within the mix acid of nitric acid in addition to hydrofluoric acid. It melts in the combination of salt 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 versions A and B. At regular temperature and atmospheric pressure, type A is just a solid round design that is body-centered. Type T tungsten is able to be found in the presence of oxygen. It’s secure to 630degC, and then transforms to a tungsten at conditions over 630degC. This technique is unreversible.


Huge difference between tungsten dust and spherical tungsten dust

Tungsten dust and tungsten spherical dust are both dust forms of tungsten, but they have obvious variations in morphology, particle measurement and application.


Tungsten dust is normally in granular form, while spherical tungsten dust is just a spherical dust after unique processing. This spherical shape enables tungsten dust to movement and fill better in applications such as 3D printing, providing more uniform printing results.

Particle Measurement

While tungsten grains have fairly big particle styles, spherical tungsten grains have really great particle styles, usually in the nanometer range. This great particle measurement enables Spherical Tungsten Powder to match better into the nozzle of the 3D printer, providing smaller print details. At the same time, the great particles will also be able to fill the print sleep, increasing the density and strength of the printed part.


Tungsten dust has a wide range of applications in several areas, such as light bulb production, technology, and mechanical parts. In these applications, tungsten dust is often used as a product or alloying element. Spherical tungsten dust, on the other give, is particularly ideal for areas such as 3D printing, wherever it is ready of making more technical, high-precision parts and products because of its exceptional flowability, stuffing influence and printability.


How will you make tungsten dust?

It’s produced by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The method of making the tungsten dust through hydrogen reduction may be divided in to two stages one period in the first period, at conditions of 500-700degC, tungsten oxide is decreased to tungsten oxide; in the second stage, at 700-900°D of which level tungsten dioxide will undoubtedly be decreased to the tungsten powder. The reduction effect is typically conducted by the form of a tube or rotary furnace.

The performance of tungsten decreased dust (such as quality in addition to particle measurement, structure, measurement, etc.) primarily depends in the technique of reduction. In the process of reducing tungsten within an range tube, the principal factors that influence the rate of reduction are conditions of reduction, number of tungsten oxide into the burner vessel and the rate of movement that the vessel is in, in addition to the rate of movement of hydrogen, and the total amount of water in hydrogen. While the conditions of reduction, measurement of tungsten dust gets more coarse.

Generation of tungsten dust combined with way of hydrogen reduction, there is also a tungsten oxide carbon reduction practices used in the beginning The reduction temperature is more than 1050 degrees Celsius.The love of the tungsten oxide dust that is produced like this is poor. Furthermore, with the use of calcium, aluminum zinc, and many other reduction processes of tungsten oxide research is currently underway. For specific applications that want ultra-fine, ultrapure particle measurement of tungsten dust the progress of the tungsten chloride hydrogen reduction process The tungsten dust particle measurement is significantly less than 0.05mm.

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

Hydrogen reduction applying tungsten trioxide hydrogen reduction may be accomplished in two measures The initial period is when tungsten trioxide heat to 550-800 , applying hydrogen reduction. The following period of reduction happens between 650 and 850 the tungsten dust is finished.

Also, it is possible to reduce ammonium paratungstate in to orange tungsten oxide (blue tungsten) initially by hydrogen, or, or even by hydrogen then lower it back once again to tungsten by hydrogen. The measurement and content of the tungsten dust are an important quality signal of the tungsten powder. The reduction process is completed through a tube or the rotary furnace.


Spherical tungsten dust has the following benefits:

Spherical shape: The spherical shape enables the tungsten dust to raised fill the print sleep throughout the printing process, providing a more uniform print result. In contrast to old-fashioned granular tungsten dust, spherical tungsten dust may better adapt to the 3D printing mind and provide a better printing process.

Great particle measurement: The great particle measurement enables the tungsten dust to raised match into the nozzle of the 3D printer, providing smaller print details. The great particles also fill the print sleep better, increasing the density and strength of the printed part.

Standard particle circulation: Standard particle circulation decreases blocking and flaws throughout the printing process and increases print success. In old-fashioned granular tungsten grains, the particle circulation is normally not uniform enough, which can cause blocking or flaws throughout the printing process. The uniform particle circulation of spherical tungsten dust may effortlessly solve this problem.

Large love: High-purity tungsten dust can provide better print efficiency and larger print quality. In certain applications, it is required to use high-purity product for printing to ensure the quality and efficiency of parts.


Spherical Tungsten Powder Program Parts

Spherical tungsten dust has a wide range of applications, including although not restricted to the following areas:

Aerospace: Spherical tungsten dust can be used to manufacture high-performance parts such as plane structural components and motor parts. In these applications, the high strength, high density and high love features of tungsten dust can provide better printing efficiency and quality.

Automotive market: Spherical tungsten is used for the manufacturing of parts for automobiles, including chassis parts, motor components and other parts. The strong longevity and weight to temperature of tungsten dust may improve printing quality and performance.

Medical subject Spherical tungsten can be used to create medical products like dental implants, surgical devices and others. The high biocompatibility in addition to the high strength of tungsten dust could improve print quality and printing performance.

Structure: Spherical tungsten dust can be used to manufacture architectural versions and components. The high strength and wear-resistant properties of tungsten dust can provide better printing efficiency and quality.

Electronics: Spherical tungsten dust can be used to manufacture electronics, such as semiconductor products, world boards and therefore on. The high thermal and electrical conductivity of tungsten dust can provide better printing efficiency and quality.

It should be noted that applying spherical tungsten dust for 3D printing needs a certain degree of ability and experience. If you’re a starter, it is advised to rehearse with even more available 3D printing components first. At the same time, applying tungsten dust for 3D printing also requires unique focus on security, as tungsten is just a high-density steel that will simply cause harm to the human body. When doing this, make sure you follow the relevant security rules and operating procedures.
