Tantalum has a series of excellent functions, such as high melting point, low steam pressure, good cold processing function, high chemical stability, strong corrosion resistance to liquid metal, large dielectric constant of surface oxide film, etc.
Therefore, tantalum has important applications in high and new technology fields such as electronics, metallurgy, steel, chemical industry, cemented carbide, atomic energy, superconducting technology, car electronics, aerospace, medical and health care and scientific research.
Between 50% and 70% of the world's tantalum is used to make tantalum capacitors in the form of capacitor grade tantalum powder and tantalum wire.
Because the appearance of tantalum can form dense amorphous oxide film stability, high dielectric strength, easy to precise manipulation of the capacitor anodic oxidation process, conveniently and tantalum powder sintering block can get a appearance of product in small volume, thus small tantalum capacitor has high capacitance, leakage current, low equivalent series resistance, good high and low temperature performance, the use of long life, inductive function well, other capacitor is difficult to match, it is widely used in communications (switches, mobile phones, pagers, fax machines, etc.), computer, car, home and office appliances, instrumentation, aerospace, national defense industry and technology.
Therefore, tantalum is an extremely versatile functional material.
