Tantalum Powder

Properties: Powder of tantalum metal, the dense oxide film generated on the surface of the powder has a unidirectional conductive valve metal property. The anode film is chemically stable (especially in acidic electrolytes), has a high resistivity (7.5 x 1010 Ω-cm), a large dielectric constant (27.6), and a small leakage current. It also has the advantages of a wide operating temperature range (-80 to 200°C), high reliability, shock resistance, and long service life. Powder production by sodium thermal reduction and hydrogen embrittlement method. Or tantalum powder is produced with a molten salt electrolyte consisting of 55% KCl - 27.5% KF - 17.5% K2TaF7. It is used to manufacture high-quality electrolytic capacitors (with a capacity more than 5 times larger than the normal capacity of the same size). It is widely used in military equipment and in high technology fields. For example, missiles, space vehicles, televisions, electronic computers, etc.

What is tantalum powder? The properties of tantalum

Ta powder is the powdered state of the metal tantalum. The chemical symbol Ta, a steel-grey metal, belongs to the VB group in the periodic table, has an atomic number of 73 and an atomic weight of 180.9479, and is a body-centered cubic crystal with a common chemical valence of +5. Tantalum has a low hardness and is related to its oxygen content, with ordinary pure tantalum having a Vickers hardness of only 140 HV in the annealed state. It has a melting point of 2995°C and ranks fifth among the monomers after carbon, tungsten, rhenium, and osmium. Tantalum is ductile and can be drawn into thin foils in the form of filaments. Its coefficient of thermal expansion is very small. It expands by only 6.6 parts per million for every degree of Celsius. In addition to this, it is very ductile, even more so than copper.

Price：

The price of tantalum powder generally varies in purity and particle size, in addition to the market trend will also affect the price of Ta powder. How much is a gram of Ta powder? All according to the day tantalum powder manufacturer quotation shall prevail.

Uses：

The dense oxide film generated on the surface has one-way conductive valve metal properties. The anode film produced is chemically stable (especially in acidic electrolytes), with a high resistivity (in acidic electrolytes). (especially in acidic electrolytes), high resistivity (7.5 x 1010Ω?cm), large dielectric constant (27.6), and small leakage current. It also has the advantages of a wide operating temperature range (-80 to 200°C), high reliability, shock resistance, long service life, etc. The powder is made by the sodium thermal reduction and hydrogen embrittlement method. Or 55% KCl-27.5% KF-17.5% K2TaF7 as a molten salt electrolyte to produce tantalum powder. It is used to manufacture high-quality electrolytic capacitors (with a capacity more than 5 times greater than the normal capacity of the same size).
