    Tantalum Powder

    Tantalum Powder
  • Tantalum Powder
  • Tantalum Powder

    Tantalum has twice the density of steel, and it is highly ductile. It has the fourth-highest melting point of all metals and can form fragile and protective oxide layers for high-quality capacitors. Our powder also has a high surface area, great handling and flow properties.
    Tantalum powder can be divided into two categories. One is capacitor tantalum, and the other is metallurgical tantalum.


    Tantalum Powder Applications

    Metallurgical tantalum is used for making tantalum foils and tantalum wires.
    Tantalum capacitors for electronic circuits are used in:
    1. Medical appliances, such as hearing aids and pacemakers.
    2. Automotive components such as ABS, airbag activation, engine management modules, GPS.
    3. Portable electronics, e.g., laptop computers, cellular/mobile phones, video cameras, digital still cameras.
    4. Other equipment such as DVD players, flat-screen TVs, games consoles, battery chargers, power rectifiers, cellular/mobile phone signal masts, oil well probes


    Capacitor Grade Tantalum Powder

    Purity: Ta >99.95% ~ 99.98% (Metal basis)

    Applications:
    1. Used to make medium to high voltage (20V-60V) solid tantalum electrolytic capacitors.
    2. Used to produce small, lightweight anodes with capacitance control.
    3. Used in medical technology.
