What is Circular Tungsten Powder?

3d printing tungsten powder is a type of tungsten that has been specifically made to printing 3D. This powder is meticulously made to make the shape of a spherical that’s why each powder compound being exceedingly homogeneous and small in size, allowing for exemplary making results.

What is tungsten powder?

Tungsten powder is a form of powdered metallic tungsten, employed as a raw material for the planning of tungsten-processed substances such as alloys, tungsten products and. It is a gray-black metal with a metallic Lustre (body-centred cubic crystal). Reduction point 3400. Boiling items 5555. The tungsten’s hardness is the absolute most difficult of the metals. The hardest tungsten pole is 200250 and it’s the hardest tungsten pole that has been spun after the rotating claw spins is 350400. It is soluble within the combine p of nitric p as well as hydrofluoric acid. It melts in the combination of sodium hydroxide and carbonate. Only a little soluble in nitric p and sulfuric p as well as aqua regia, insoluble in hydrofluoric p and water. potassium hydroxide. Tungsten has two kinds A and B. At usual temperature and atmospheric stress, type A is a solid round framework that’s body-centered. Form W tungsten is ready can be found in the presence of oxygen. It is secure to 630degC, and then turns to a tungsten at temperatures above 630degC. This method is unreversible.

Huge difference between tungsten powder and spherical tungsten powder

Tungsten powder and tungsten spherical powder are both powder types of tungsten, but they have obvious differences in morphology, compound measurement and application.


Tungsten powder is generally in granular type, while spherical tungsten powder is a spherical powder following particular processing. This spherical shape allows tungsten powder to flow and fill greater in applications such as 3D making, giving more uniform making results.

Particle Measurement

While tungsten grains have fairly large compound shapes, spherical tungsten grains have very great compound shapes, usually in the nanometer range. This great compound measurement allows Spherical Tungsten Powder to fit greater in to the nozzle of the 3D printer, giving finer printing details. At the same time, the great contaminants will also be able to fill the printing bed, increasing the density and power of the printed part.


Tungsten powder features a wide selection of applications in several fields, such as lamp manufacturing, technology, and technical parts. In these applications, tungsten powder is frequently applied as a product or alloying element. Spherical tungsten powder, on another give, is specially suited to areas such as 3D making, wherever it’s ready of creating more technical, high-precision areas and units because of its exemplary flowability, stuffing impact and printability.

How do you prepare tungsten powder?

It is produced by the hydrocarbon decrease on tungsten trioxide, or ammonium paratungstate. The method of creating the tungsten powder through hydrogen decrease may be divided into two phases one stage in the initial stage, at temperatures of 500-700degC, tungsten oxide is reduced to tungsten oxide; in the next phase, at 700-900°C where point tungsten dioxide will be reduced to the tungsten powder. The decrease reaction is normally done by the shape of a tube or rotary furnace.

The effectiveness of tungsten reduced powder (such as quality as well as compound measurement, arrangement, measurement, etc.) largely depends in the technique of reduction. In the act of reducing tungsten in a stove pipe, the primary facets that influence the rate of decrease are temperatures of decrease, number of tungsten oxide in to the burner vessel and the pace of movement that the vessel is in, as well as the rate of flow of hydrogen, and the total amount of humidity in hydrogen. As the temperatures of decrease, measurement of tungsten powder gets more coarse.

Creation of tungsten powder combined with the way of hydrogen decrease, there is also a tungsten oxide carbon decrease techniques employed at first The decrease temperature is more than 1050 degrees Celsius.The purity of the tungsten oxide powder that’s made using this method is poor. Moreover, with the usage of calcium, metal zinc, and several other decrease operations of tungsten oxide study happens to be underway. For particular applications that want ultra-fine, ultrapure compound measurement of tungsten powder the growth of the tungsten chloride hydrogen decrease process The tungsten powder compound measurement is less than 0.05mm.

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

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

Also, it’s possible to reduce ammonium paratungstate into orange tungsten oxide (blue tungsten) initially by hydrogen, or, if not by hydrogen then minimize it back once again to tungsten by hydrogen. The measurement and content of the tungsten powder are a significant quality signal of the tungsten powder. The decrease process is completed via a pipe or the rotary furnace.

Spherical tungsten powder has these benefits:

Spherical shape: The spherical shape allows the tungsten powder to raised fill the printing bed through the making process, giving a more uniform printing result. Compared with conventional granular tungsten powder, spherical tungsten powder may greater conform to the 3D making mind and offer a softer making process.

Fine compound measurement: The great compound measurement allows the tungsten powder to raised match in to the nozzle of the 3D printer, giving finer printing details. The great contaminants also fill the printing bed greater, increasing the density and power of the printed part.

Uniform compound circulation: Uniform compound circulation reduces blocking and defects through the making process and improves printing success. In conventional granular tungsten grains, the compound circulation is generally not uniform enough, that may result in blocking or defects through the making process. The uniform compound circulation of spherical tungsten powder may effectively solve that problem.

High purity: High-purity tungsten powder provides greater printing performance and larger printing quality. In a few applications, it’s essential to make use of high-purity material for making to guarantee the quality and performance of parts.

Spherical Tungsten Powder Application Parts

Spherical tungsten powder features a wide selection of applications, including however not limited to these areas:

Aerospace: Spherical tungsten powder can be used to manufacture high-performance areas such as plane architectural components and engine parts. In these applications, the large power, large density and large purity traits of tungsten powder provides greater making performance and quality.

Automotive business: Spherical tungsten is useful for the manufacturing of areas for automobiles, including framework areas, engine components and different parts. The powerful durability and opposition to temperature of tungsten powder will increase making quality and performance.

Medical subject Spherical tungsten can be used to create medical units like dental implants, surgical devices and others. The large biocompatibility as well as the large power of tungsten powder could increase printing quality and making performance.

Structure: Spherical tungsten powder can be used to manufacture architectural types and components. The large power and wear-resistant homes of tungsten powder provides greater making performance and quality.

Technology: Spherical tungsten powder can be used to manufacture gadgets, such as semiconductor units, circuit panels and so on. The large thermal and electric conductivity of tungsten powder provides greater making performance and quality.

It must be noted that applying spherical tungsten powder for 3D making takes a particular level of ability and experience. If you are a novice, it is advised to apply with some more available 3D making resources first. At the same time, applying tungsten powder for 3D making also involves particular focus on safety, as tungsten is a high-density metal that could quickly trigger injury to the individual body. When doing this, make sure you follow the relevant safety rules and operating procedures.
