Tantalum Powder For Metallurgical Grade

We are offering our customers a wide range of Tantalum Powder for Metallurgical Grade, which are available following Specifications :-
Appearance: Dark grey powder
Application: Manufacturing Tantalum foil and wire etc
Purity:99.9%;99.95%;99.99%.
Nature: Tantalum powder, the powder surface of the compact oxide film has a one-way conductive valve metal nature. Made stable chemical properties of the anodic film (especially stable in the acidic electrolyte), high electrical resistivity, dielectric constant (27.6), low leakage current. Also has a wide operating temperature range (-80 ~ 200 a ), high reliability, seismic and long life advantages. Through sodium thermal reduction and hydrogen embrittlement of the legal system to make the powder, and used to produce high-quality electrolytic capacitors (capacitance than the same size as ordinary, large capacity for more than five times). Widely used in military equipment and high-tech fields. Such as missiles, space vehicles, TV, computer.
