  2. Tantalum - Wikipedia

    en.wikipedia.org/wiki/Tantalum

    Tantalum pentoxide (Ta 2 O 5) is the most important compound from the perspective of applications. Oxides of tantalum in lower oxidation states are numerous, including many defect structures, and are lightly studied or poorly characterized. [38] Tantalates, compounds containing [TaO 4] 3− or [TaO 3] − are numerous.

  3. Tantalum capacitor - Wikipedia

    en.wikipedia.org/wiki/Tantalum_capacitor

    The next stage for solid tantalum capacitors is the application of the cathode plate (wet tantalum capacitors use a liquid electrolyte as a cathode in conjunction with their casing). This is achieved by pyrolysis of manganese nitrate into manganese dioxide. The "pellet" is dipped into an aqueous solution of nitrate and then baked in an oven at ...

    en.wikipedia.org/wiki/Tantalum_pentoxide

    Tantalum ores often contain significant amounts of niobium, which is itself a valuable metal.As such, both metals are extracted so that they may be sold. The overall process is one of hydrometallurgy and begins with a leaching step; in which the ore is treated with hydrofluoric acid and sulfuric acid to produce water-soluble hydrogen fluorides, such as the heptafluorotantalate.

  5. Tantalum carbide - Wikipedia

    en.wikipedia.org/wiki/Tantalum_carbide

    Tantalum carbide is widely used as sintering additive in ultra-high temperature ceramics (UHTCs) or as a ceramic reinforcement in high-entropy alloys (HEAs) due to its excellent physical properties in melting point, hardness, elastic modulus, thermal conductivity, thermal shock resistance, and chemical stability, which makes it a desirable ...
