Purpose: used for making heating parts and heat insulating parts of vacuum blast furnace, it can be used for making digester, heater, cooler, various utensils and devices in chemical industry, and widely used in aviation, aerospace industry, medical equipment and other fields.
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 large dielectric constant of surface oxide film. Therefore, tantalum has important applications in electronics, metallurgy, steel, chemical industry, hard alloy, atomic energy, superconducting technology, automotive electronics, aerospace, medical and health, scientific research and other high-tech fields.
Between 50% and 70% of tantalum in the world is used to make tantalum capacitors in the form of capacitor grade tantalum powder and tantalum wire. Because of the compact tantalum surface can form stable, high dielectric strength of amorphous oxide film, and is easy to be accurate and easily control capacitor anodic oxidation process, at the same time, tantalum powder sintering block can be obtained in a very small volume, large surface area so small tantalum capacitor has high capacitance, leakage current, low equivalent series resistance, good high and low temperature performance, long service life, excellent comprehensive performance, other capacitor is difficult to match, it is widely used in communications (switches, mobile phones, pagers, fax machines, etc.), computer, automobile, household and office appliances, instrumentation, aerospace, national defense industry and technology sector, etc. So tantalum is an extremely versatile functional material.
