99.95%min Tantalum Wire Metal Tantalum Ta Wire For Electronic Laboratory Researc
Description:
Tantalum is dark, dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity.
The metal is renowned for its resistance ,as the metal powder, is in the production of electronic components, mainly capacitors and some high-power resistors.
Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer,
using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate".
Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume.
Because of the size and weight advantages, tantalum capacitors are attractive for portable telephones, personal computers, and automotive electronics.

Application:
The characteristics of tantalum make its application field very broad. In the equipment for preparing various inorganic acids, tantalum can be used to replace stainless steel, and its life span can be increased by several tens of times compared with stainless steel.
In addition, in the chemical, electronic, electrical and other industries, tantalum can replace the precious metal platinum in the past, which greatly reduces the cost. Tantalum is manufactured into capacitors and used in military equipment.
Specification:
Tantalum is one of the rare metal mineral resources and an indispensable strategic raw material for the development of the electronics industry and space technology.
