    Tantalum Application

    Source: https://www.tanb.org/about-tantalum/applications-for-tantalum

    Tantalum consumption is dominated by capacitors for electronic equipment. Capacitors are electrical components that store energy electrostatically in an electric field, and are used in a wide variety of electric and electronic products. Capacitors are an essential part of almost all electronic products, ranging from smart phones to appliances in our homes, electronic systems in our cars and wind turbines producing electricity.

    Additionally, tantalum wire is consumed by the capacitor manufacturers as the anode lead. Tantalum metal is also used for sintering tray assemblies and shielding components for the anode sintering furnaces.

    Capacitor grade tantalum powder provides about 25% of the market use of all tantalum shipments. Additional quantities related to capacitors are consumed by tantalum wire for the anode lead as well as for sintering tray assemblies and shielding components for the anode sintering furnaces.

    Other non-capacitor uses in electronics create demand for tantalum mill products for sputtering targets and tantalum chemicals for audio and video components.

    Tantalum Product
    Application
    Technical Attributes/Benefits

    Tantalum oxide
    - Lenses for spectacles, digital cameras and mobile phones
    - X-ray film
    - Ink jet printers
    - Ta2O5 provides a high index of refraction so lenses for a given focal strength can be thinner and smaller
    - Yttrium tantalate phosphor reduces X-ray exposure and enhances image quality
    - Wear resistance characteristics. Integrated capacitors in integrated circuits (ICs)
    Tantalum powder
    Tantalum capacitors for electronic circuits in:
    - medical appliances such as hearing aids and pacemakers;
    - automotive components such as ABS, airbag activation, engine management modules, GPS;
    - portable electronics e.g. laptop computers, cellular/mobile phones, video cameras, digital still cameras;
    - other equipment such as DVD players, flat screen TVs, games consoles, battery chargers, power rectifiers, cellular/mobile phone signal masts, oil well probes
