Spherical tantalum powder application
Tantalum has excellent biocompatibility, and tantalum implants formed by 3D printing have the elastic modulus closest to human cartilage tissue, making them the most ideal orthopedic implant materials.  Rf plasma spheroidized tantalum powder has the characteristics of high sphericity, good fluidity, high purity, large loose density, full density inside particles, no hollow powder, etc., which is widely used in biomedical field.  
Spherical tantalum powder, or tantalum powder for short, is prepared from tantalum metal as raw material. It has excellent physical and chemical properties and, therefore, has many applications in many fields. The main application fields of spherical tantalum powder will be introduced below.

High-performance capacitors
Spherical tantalum powder is widely used in electronic equipment to manufacture high-performance capacitors. Tantalum capacitors have the advantages of small size, large capacity, good stability, and excellent temperature characteristics. Therefore, they are widely used in various electronic products such as mobile phones, computers, and consumer electronics. Spherical tantalum powder can improve the density and performance of capacitors, reduce energy consumption and heat generation of equipment, and improve the reliability and stability of equipment.

Wear-resistant materials
Spherical tantalum powder has excellent wear resistance and high-temperature strength, so it is a high-performance, wear-resistant material for various mechanical equipment. For example, in high-wear components such as bearings, gears, and turbines, wear-resistant coatings made of tantalum powder can significantly improve the life and performance of these components and reduce equipment maintenance costs.

High-temperature corrosion-resistant materials
Tantalum powder has excellent high-temperature stability and corrosion resistance and can be used in high-temperature and highly corrosive environments. Therefore, it can be used as a protective coating or structural material in some special environments, such as high-temperature corrosion environments in blast furnaces, heat treatment equipment, aerospace engines, etc., to improve the durability and safety of equipment.

Electronic paste
Spherical tantalum powder is used in the electronics industry as the main raw material for electronic slurries to manufacture thick film integrated circuits and integrated circuits. Through screen printing technology, tantalum powder is mixed with other metal oxides to make an electronic paste, which can easily produce various electronic components and circuits, with the advantages of high production efficiency and low cost.

Biomedical field
Spherical tantalum powder has excellent biocompatibility and corrosion resistance, so it is also widely used in the biomedical field. It can manufacture biomedical materials, such as implantable medical devices, biosensors, drug carriers, etc. At the same time, tantalum is also a good electrochemical energy storage material, so it can be used to manufacture energy storage devices in the biomedical field, such as pacemakers and neurostimulators.

Powder metallurgy field
Spherical tantalum powder is a raw material for preparing high-performance metal powders in powder metallurgy. Mixing tantalum powder with other metal powders can produce composite materials and alloys with excellent properties. For example, tantalum-based alloys have high melting points, density, and strength, so they have broad application prospects in aerospace, military, and other fields.

Surface coating technology
Spherical tantalum powder can be used to prepare high-density, high-bonding metal coatings. Using techniques such as physical or chemical vapor deposition, tantalum powder is made into a coating, which can significantly improve the material's surface hardness, wear resistance, corrosion resistance, and high-temperature stability. This coating technology is widely used in aerospace, automotive, energy, and other fields.

Composition (percentage by mass):

Storage Condition of Spherical Tantalum Powder:

Damp reunion will affect Spherical Tantalum powder dispersion performance and using effects, therefore,Spherical Tantalum Powder should be sealed in vacuum packing and stored in cool and dry room, the Spherical Tantalum Powder can not be exposure to air. In addition, the Spherical Tantalum powder should be avoided under stress.

How to produce  Spherical Tantalum Powder

High-purity tantalum ingots are bombarded with high-temperature secondary electron beams as raw hydrogenation and absorption materials.

The tantalum powder particles are ground and sieved by a ball mill to pass through different meshes to obtain standard sieved tantalum powder.

After dehydrogenation treatment, a jet mill is used for airflow molding to obtain a raw powder with an improved appearance.

After removing impurities by pickling, air heat treatment, magnesium reduction, and oxygen reduction are performed to obtain spherical/quasi-spherical tantalum powder.

Re-spheroidization with plasma equipment
