Tantalum metal Applications
Tantalum with high melting point, low steam, cold work performance is good, high chemical stability and liquid metal corrosion resistance is strong, large surface oxidation film dielectric constant and a series of excellent performance.Therefore, tantalum in electronics, metallurgy, steel, chemical, hard alloy, atomic energy, superconducting technology, automotive electronics, aerospace, medical and scientific research and other high-tech fields have important applications.
Between 50% and 70% of tantalum in the world in the form of capacitor grade tantalum powder and tantalum wire is used for making tantalum capacitors.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 materials.
