Tantalum powder is a dark grey, combustible metal powder. There are three primary types, each has a distinct physical shape and is derived from a unique process. Nodular tantalum powder is made by molten sodium reduction of tantalum salt or solid magnesium reduction of tantalum (V) oxide.
American Elements specializes in producing high purity Tantalum Powder with the smallest possible average grain sizes for use in preparation of pressed and bonded sputtering targets and in Chemical Vapor Deposition (CVD) and Physical Vapor Deposition (PVD) processes including Thermal and Electron Beam (E-Beam) Evaporation, Low Temperature Organic Evaporation, Atomic Layer Deposition (ALD),
Medical tantalum powder is used in the preparation of medical porous tantalum implant materials. Its high sintering strength, uniform porous tantalum pore size after producing, stable mechanical properties, high purity, and good biocompatibility make tantalum powder become an ideal material for human bones.

Capacitor grade tantalum powder which is to be sintered into a porous anode and electrolytically formed, the powder being of such size, configuration and composition so that the sintered at 1.400° C or higher and formed anodes can achieve a high specific capacitance (CV/gm) in excess of 15.000 CV/gm,
Fine tantalum respectively niobium powders of high purity are required for the production of such capacitors. This approach allowed us to explore factors that explain the use of emerging peer
Methods of forming tantalum powders and other valve metal powders are described. The method involves high impact milling a starting powder in a fluid medium and optionally a milling media using a high energy mill. The methods of the present invention have the ability to reduce DC leakage and/or increase capacitance capabilities of valve metal powders when formed into capacitor anodes.
Capacitor grade powders in the nodular, flake and angular morphologies, are found in a variety of electronics applications. Capacitance values for the GAM produced tantalum capacitor grade powders range from 1,000 CV/g up to 300,000 CV/g.
Our tantalum powders with lower specific surface areas (up to approx. 1.5 m 2 /g) and larger grain sizes, which can be used to manufacture low to medium capacitance tantalum capacitors for medium to high working voltages, are particularly suitable for use in the production of capacitors for consumer electronic devices, where reliability is more
