Ta, Tantalum Mineral Analysis

Tantalum is a gray, hard and ductile metal. It can be made into a fine wire in its pure state. Tantalum is fully immune to chemical attacks at temperatures below 150 degrees. Tantalum oxide films are very stable and have good rectifier and dielectric properties. Its melting point is extremely high and it becomes much more reactive at high temperatures.

Tantalum is obtained from mineral found in naturally occurring columbite-tantalite. This mineral is mostly found in Australia, Brazil, Mozambique, Thailand, Portugal, Nigeria and Canada. To remove tantalum from niobium, electrolysis, potassium fluorotantalate should be reduced with sodium or carbide should be reacted with oxide.

Tantalum is used in various alloys to obtain high strength, ductility or obtain a high melting point. For example, a thin cable is brought into its state and used as a filament to evaporate metals such as aluminum. More than half of the tantalum obtained is for producing electrolytic capacitors and vacuum oven parts. It is also used to make tantalum, chemical process equipment, nuclear reactors, aircraft and missile parts.

Tantalum is also preferred in the construction of surgical devices, as it is completely immune to body fluids. It is also used in the production of special glass with high refractive index for equipment parts such as tantalum oxide, camera lenses.

Briefly tantalum has become an important element especially in the electronics industry. More than 75 percent of electronics have a tantalum structure. In particular, engineers use the properties of tantalum to make capacitors and other components smaller and more efficient.
