Capacitor Grade Tantalum Powder Description
SAM offers high-quality capacitor grade tantalum powder (4V-40V) produced using sodium reduction processes. Tantalum has twice the density of steel and it is highly ductile. It has the fourth-highest melting point of all metals and is able to form extremely thin and protective oxide layers for high-quality capacitors. Our powder also has a high surface area and great handling and flow properties.

Capacitor Grade Tantalum Powder Properties
Capacitor-grade tantalum powder is a high-purity material used specifically in the production of tantalum capacitors.
• High Purity: The powder has extremely high purity, typically greater than 99.95%, to ensure reliable performance in capacitors.
• Particle Size and Shape: The powder particles are fine and have a specific size distribution, often in the range of 1 to 10 micrometers, with a uniform spherical or angular shape for optimal packing and performance.
• High Surface Area: A large surface area to volume ratio is essential for high capacitance values, which is achieved by having small and uniformly shaped particles.
• High Capacitance Efficiency: The material's intrinsic properties enable high capacitance per unit volume, making it suitable for compact and efficient capacitor designs.
• Low Leakage Current: The high purity and controlled particle size help in reducing the leakage current, ensuring better performance and reliability of the capacitors.
• Good Sintering Properties: Tantalum powder used for capacitors must sinter well to form a dense, stable anode structure during the manufacturing process.
• Consistent Performance: The powder is manufactured to provide consistent electrical performance, ensuring that capacitors have reliable and predictable characteristics.
These properties make capacitor-grade tantalum powder an ideal material for producing high-performance, reliable tantalum capacitors used in various electronic applications.
