Features of High purity tantalum metal powder Non spherical Ta powder CAS7440-25-7
Physical Characteristics
Particle Size: Ranging from nanometers to hundreds of micrometers, the size distribution significantly influences the powder’s flowability, packing density, and sintering behavior.
Shape: Particles can be spherical, irregular, flake-like, or dendritic, each shape affecting the final product’s mechanical properties and surface finish.
Purity: Depending on the production method, metal powders can achieve high levels of purity, critical for applications like electronics and aerospace where impurities can degrade performance.
Density: While less dense than their solid counterparts due to the presence of air between particles, metal powders can be densely packed during processing to approach the density of the solid metal.
Chemical Properties
Reactivity: Some metal powders, particularly aluminum and titanium, are highly reactive with air and moisture, necessitating careful handling and storage under inert atmospheres or vacuum.
Oxidation: Exposure to air can lead to surface oxidation, forming a passive layer that affects sintering and other processes. This can be managed through surface treatment or use of protective atmospheres.

Parameters of High purity tantalum metal powder Non spherical Ta powder CAS7440-25-7
Tantalum, a chemical element with the symbol Ta and atomic number 73, is a rare, lustrous transition metal that holds exceptional properties due to its unique combination of strength, corrosion resistance, and high melting point. The high purity tantalum metal powder, specifically Non-Spherical Ta Powder with the CAS number 7440-25-7, is a material of great interest in various industrial applications.
This particular tantalum powder form is characterized by its non-spherical shape, which offers distinct advantages over traditional spherical powders. The non-spherical particles provide improved flowability, reduced agglomeration, and enhanced surface area, leading to better dispersion in various matrices. This feature is particularly beneficial in applications where precise mixing and compaction are critical, such as in advanced ceramics, aerospace, and electronic components.
The purity of this tantalum powder is a key selling point, as it ensures minimal impurities and reduces contamination during processing. High purity tantalum is known for its inherent stability, making it resistant to corrosion from acids and alkalis, even at elevated temperatures. This makes it ideal for use in harsh environments, like chemical processing equipment, medical implants, and nuclear reactors.
The high melting point of tantalum (3017°C or 5452°F) further contributes to its durability and resistance to deformation under extreme conditions. It is often used in applications requiring high thermal stability, such as heat sinks, crucibles for high-temperature reactions, and electronic components exposed to high temperatures.
In the electronics industry, tantalum is utilized in capacitors due to its low dielectric loss and superior self-healing capabilities, which minimize the risk of failure over time. Additionally, tantalum’s excellent conductivity and magnetic properties make it suitable for use in high-frequency devices and superconducting magnets.
In the aerospace sector, tantalum finds application in lightweight structural components, thanks to its high strength-to-weight ratio. It is also employed in jet engine parts, where its resistance to thermal expansion and erosion is crucial for maintaining optimal performance.
The non-spherical tantalum powder’s versatility extends to the field of biomedical engineering, where it can be used in implantable devices due to its biocompatibility and long-term stability. Tantalum has been found to have acceptable tissue response, making it an attractive material for orthopedic and dental implants.
In summary, high purity Non-Spherical Ta Powder with CAS number 7440-25-7 is a premium material with exceptional properties, including improved flow characteristics, high purity, and outstanding mechanical and chemical stability. Its unique shape and inherent benefits make it a sought-after component in diverse industries, from electronics and aerospace to medicine and energy. As technology continues to advance, the demand for this versatile tantalum powder is likely to grow, driven by its ability to withstand demanding conditions and enable innovative solutions.
