In its elemental form, tantalum has a grayish blue appearance. Tantalum is found in the minerals tantalite, microlite, wodginite, euxenite, and polycrase. Due to the close relation of tantalum to niobium in the periodic table, Tantalum's name originates from the Greek word Tantalos meaning Father of Niobe in Greek mythology. Tantalum Capacitor Powder is a high-performing, cost-effective alternative to ceramin and aluminum-based capacitor materials. Niobium monoxide capacitor powder is generally immediately available in most volumes, including bulk orders.
Dr. Willem-Jan de Kleijn Ph.D, (Luleå University of Technology, Luleå, Sweden) One of the major uses of Tantalum powder is in the production of electronic components.On the surface of tantalum, an oxide layer is formed can act as an insulating (dielectric) layer.Because tantalum can be utilized to coat other metals with a very thin layer, a high capacitance can be attained in a small volume. Tantalum metal powder, including the precursor to capacitor grade powder, is generally produced by the sodium reduction of the potassium tantalum fluoride in a molten salt system at high temperature. The metal can also be produced by the carbon or aluminium reduction of the oxide or the hydrogen or alkaline earth reduction of tantalum chloride.
