Overview

Tantalum (Ta) General Information：

Tantalum chemical symbol Ta, steel gray metal, VB family in periodic table, atomic number 73, atomic weight 180. 9479, body-centered cubic crystal, common valence is + 5. Tantalum is low in hardness and oxygen content-dependent, ordinary pure tantalum, annealed Vickers hardness of only 140 hv. Its melting point is as high as 2995 ° C, ranking the fifth among the simple substances, after carbon, tungsten, rhenium and osmium. Tantalum is very malleable and can be drawn into a thin-wire case. It's a small Coefficient of thermal expansion. It only expands by 6.6 parts per million per degree Celsius. In addition, its toughness is very strong, even better than copper.

Tantalum is mainly found in tantalite and coexists with niobium. Tantalum has moderate hardness and good ductility, and can be drawn into thin foil of fine wire type. It's a small Coefficient of thermal expansion. Tantalum is highly chemical property and highly resistant to corrosion. It does not react with hydrochloric acid, concentrated nitric acid or aqua regia in both hot and cold conditions. It can be used to make evaporator and so on. It can also be used as electrode of electron tube, rectifier and electrolytic capacitor. Used medically to make sheets or threads to sew up damaged tissue. Although tantalum is highly resistant to corrosion, its resistance to corrosion is due to the formation of a stable tantalum pentoxide (TA205) protective film on its surface.

Tantalum has a wide range of applications due to its unique properties.

Tantalum can be used as a substitute for stainless steel in the production of various inorganic acids.

In addition, in the chemical, electronic, electrical and other industries,

tantalum can replace the past need to take on the task of the precious metal platinum,

Tantalum is manufactured as a capacitor for use in military equipment.

Half of the world's tantalum production is used in the production of tantalum capacitors.
