  2. Tantalum pentoxide - Wikipedia

    en.wikipedia.org/wiki/Tantalum_pentoxide

    Tantalum pentoxide, also known as tantalum(V) oxide, is the inorganic compound with the formula Ta 2 O 5. It is a white solid that is insoluble in all solvents but is attacked by strong bases and hydrofluoric acid. Ta 2 O 5 is an inert material with a high refractive index and low absorption (i.e. colourless), which makes it useful for coatings ...

    Most common is the pentoxide, also being precursor to almost all niobium compounds and alloys. [26] [32] 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. [31]

  6. Tantalum capacitor - Wikipedia

    en.wikipedia.org/wiki/Tantalum_capacitor

    A typical tantalum capacitor is a chip capacitor and consists of tantalum powder pressed and sintered into a pellet as the anode of the capacitor, with the oxide layer of tantalum pentoxide as a dielectric, and a solid manganese dioxide electrolyte as the cathode.

  7. Tantalum(V) chloride - Wikipedia

    en.wikipedia.org/wiki/Tantalum(V)_chloride

    It takes the form of a white powder and is commonly used as a starting material in tantalum chemistry. It readily hydrolyzes to form tantalum(V) oxychloride (TaOCl 3) and eventually tantalum pentoxide (Ta 2 O 5); this requires that it be synthesised and manipulated under anhydrous conditions, using air-free techniques.
