Overview of high purity Tantalum powder Scientific research materials and metal powder
Tantalum (Ta) is a chemical element with the atomic number 73 and is symbolized as Ta on the periodic table. It is a dense, blue-gray, hard, and ductile transition metal. Discovered in 1802 by Anders Gustaf Ekeberg, tantalum is renowned for its high resistance to corrosion and its ability to store and release electrical charges efficiently, making it a critical material in various high-tech applications.
Feature of high purity Tantalum powder Scientific research materials and metal powder
-
Exceptional Corrosion Resistance: Tantalum forms a protective oxide layer that shields the metal from most acids, even at high temperatures, and is virtually impervious to chemical attacks.
-
High Melting Point: With a melting point of approximately 3,017°C (5,462°F), tantalum ranks among the metals with the highest melting points, enabling its use in extreme temperature environments.
-
Biocompatibility: Tantalum is well-tolerated by living tissue, making it suitable for biomedical implants such as bone replacements and surgical sutures.
-
Electrical Conductivity: Although not the best conductor, tantalum has a high capacitance per volume, making it ideal for manufacturing compact capacitors used in electronic devices.
-
Ductility: It can be drawn into fine wires and fabricated into various shapes without fracturing, a feature that enhances its versatility in manufacturing.

Parameters of high purity Tantalum powder Scientific research materials and metal powder
Tantalum powder is a scientific research material that is used for various purposes, including catalytic activity, heat dissipation, and the production of electronic devices. It is a high-purity powder with a density of about 98%, making it very lightweight and strong.
In terms of parameters, there are several important factors to consider when working with tantalum powder:
1. Tantalum content: The purity of the tantalum powder will depend on its percentage. High purity tantalum powder typically has a concentration between 95% and 99.5%. This can be determined by analyzing the X-ray diffraction (XRD) pattern of the powder using a specialized XRD instrument.
2. Particle size: The particle size of tantalum powder can affect its behavior in different applications. Smaller particles have better thermal conductivity and resistance to corrosion, while larger particles may create aggregates or reduce the surface area available for reactions.
3. Content of impurities: The presence of impurities in tantalum powder can affect its performance, such as increasing the amount of reactivity and reducing its compatibility with other materials.
4. Optical properties: Tantalum powder also exhibits unique optical properties, such as the formation of nanocrystalline structures that give it exceptional electrical and magnetic properties.
Overall, the use of tantalum powder in scientific research requires careful consideration of these parameters to ensure that the powder meets the desired specifications and performs optimally in the intended application.
