Tantalum has a high melting point, low vapor pressure, small expansion coefficient, good processing performance, good thermal stability, excellent dielectric properties, can be used as electrolytic capacitors, tantalum is a good material for high-power electronic tube parts, can be used as anode, gate, cathode.
1. Tantalum has good chemical corrosion resistance at high temperatures, more stable in strong acids. Mostly used for making vacuum blast furnace with heating parts, heat insulation parts, in the chemical industry can be used to make the cooker, heater, cooler, all kinds of utensils devices, etc., as well as in the aviation, aerospace industry, medical equipment and other fields have a wide range of applications.
2. Tantalum has a series of excellent properties such as high melting point, low vapor pressure, good cold working performance, high chemical stability, strong resistance to liquid metal corrosion, and high dielectric constant of surface oxide film. Therefore, tantalum has important applications in high-tech fields such as electronics, metallurgy, iron and steel, chemical industry, cemented carbide, atomic energy, superconducting technology, automotive electronics, aerospace, medical and health care and scientific research.
3. 50%-70% of the world's tantalum in the form of capacitor-grade tantalum powder and tantalum wire is used to make tantalum capacitors.
