What is Spherical Tungsten Powder?

Spherical tungsten powder the type of tungsten that has been specifically designed to print 3D. This powder is meticulously made to form the model of a spherical that is why each powder particle being extremely homogeneous and small in proportions, making it possible for excellent printing results.

What is Tungsten Powder?

Tungsten powder is a type of powdered metallic tungsten, utilized being a raw material for the preparation of tungsten-processed substances such as alloys, tungsten products and. It is a gray-black metal having a metallic Lustre (body-centred cubic crystal). Melting point 3400. Boiling points 5555. The tungsten’s hardness is easily the most hard of the metals. The most challenging tungsten rod is 200250 which is the most difficult tungsten rod which has been spun after the spinning hammer spins is 350400. It is actually soluble in the mix acid of nitric acid as well as hydrofluoric acid. It melts inside the mixture of sodium hydroxide and carbonate. A bit soluble in nitric acid and sulfuric acid as well as aqua regia, insoluble in hydrofluoric acid and water. potassium hydroxide. Tungsten has two varieties A and B. At normal temperature and atmospheric pressure, type A is really a solid cylindrical structure that is body-centered. Type B tungsten is able to be located in the presence of oxygen. It can be stable to 630degC, after which transforms to your tungsten at temperatures above 630degC. This process is unreversible.

Difference between tungsten powder and spherical tungsten powder

Tungsten powder and tungsten spherical powder are both powder sorts of tungsten, however they have obvious differences in morphology, particle size and application.

Morphology

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

Particle Size

While tungsten powders have relatively large particle sizes, spherical tungsten powders have very fine particle sizes, usually inside the nanometer range. This fine particle size allows 3D printed tungsten to put better in to the nozzle from the 3D printer, providing finer print details. As well, the fine particles may also be capable to fill the print bed, improving the density and strength in the printed part.

Applications

Tungsten powder has a variety of applications in numerous fields, including light bulb manufacturing, electronics, and mechanical parts. In these applications, tungsten powder is frequently used like a filler or alloying element. Spherical tungsten powder, in the other hand, is extremely appropriate for areas such as 3D printing, where it is capable of creating more complicated, high-precision parts and devices for its excellent flowability, filling effect and printability.

How would you prepare tungsten powder?

It is created by the hydrocarbon reduction on tungsten trioxide, or ammonium paratungstate. The entire process of making the tungsten powder through hydrogen reduction may be divided into two phases one stage within the first stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; from the second phase, at 700-900°C at which point tungsten dioxide will be reduced for the tungsten powder. The reduction reaction is typically performed by the shape of a tube or rotary furnace.

The efficiency of tungsten reduced powder (like quality and also particle size, composition, size, etc.) mostly depends from the means of reduction. In the process of reducing tungsten in an oven tube, the main factors affecting the velocity of reduction are temperatures of reduction, quantity of tungsten oxide in to the burner vessel and the speed of motion the vessel is, as well as the rate of flow of hydrogen, and the level of moisture in hydrogen. Because the temperatures of reduction, scale of tungsten powder gets more coarse.

Manufacture of tungsten powder together with the approach to hydrogen reduction, there is also a tungsten oxide carbon reduction methods employed in the beginning The reduction temperature is greater than 1050 degrees Celsius . The purity in the tungsten oxide powder that is produced employing this method is poor. Furthermore, by using calcium, aluminum zinc, as well as other reduction processes of tungsten oxide research is currently underway. For specific applications that need ultra-fine, ultrapure particle dimensions of tungsten powder the creation of the tungsten chloride hydrogen reduction process The tungsten powder particle dimensions are less than .05mm.

Industrial production can be achieved from the decrease in tungsten trioxide by hydrogen, or ammonium partungstate is addressed with acid after which tungsten trioxide can be created by maturation decomposition then reduced using hydrogen.

Hydrogen reduction using tungsten trioxide hydrogen reduction can be achieved in 2 steps The very first stage takes place when tungsten trioxide heating to 550-800 , using hydrogen reduction. The subsequent stage of reduction occurs between 650 and 850 the tungsten powder is finished.

Also, it really is easy to reduce ammonium paratungstate into blue tungsten oxide (blue tungsten) initially by hydrogen, or, or even by hydrogen then reduce it back to tungsten by hydrogen. The dimensions and content of the tungsten powder are an important quality indicator from the tungsten powder. The reduction process is conducted via a tube or maybe the rotary furnace.

Spherical tungsten powder provides the following advantages:

Spherical shape: The spherical shape allows the tungsten powder to higher fill the print bed during the printing process, providing a far more uniform print result. Compared with traditional granular tungsten powder, spherical tungsten powder can better adapt to the 3D printing head and provide a smoother printing process.

Fine particle size: The fine particle size allows the tungsten powder to better match the nozzle in the 3D printer, providing finer print details. The fine particles also fill paper bed better, improving the density and strength from the printed part.

Uniform particle distribution: Uniform particle distribution reduces clogging and defects in the printing process and improves print success. In traditional granular tungsten powders, the particle distribution is generally not uniform enough, which can cause clogging or defects through the printing process. The uniform particle distribution of spherical tungsten powder can effectively solve this concern.

High purity: High-purity tungsten powder can provide better print performance and better print quality. In many applications, it is required to use high-purity material for printing to be sure the quality and gratifaction of parts.

Spherical Tungsten Powder Application Areas

It needs to be noted that using spherical tungsten powder for 3D printing takes a certain amount of skill and experience. Should you be a newbie, it is strongly recommended to apply with some more accessible 3D printing materials first. As well, using tungsten powder for 3D printing also requires special focus on safety, as tungsten can be a high-density metal that may easily cause damage to the human body. When you are performing so, make sure you adhere to the relevant safety regulations and operating procedures.
