Tantalum plate is rich in ductility and can be pulled into a filament type thin foil. Its thermal expansion coefficient is small, the rising of one degree, it can swell only six point six of a million. In addition, its toughness is very strong, it is superior than copper. Tantalum plate also has excellent chemical properties and high corrosion resistance.
The characteristics of tantalum plate make it have broad application. In the equipment of making various inorganic acid, tantalum plate can be used to replace stainless steel, its life can be improved by several times than stainless steel. In addition, in the chemical, electronic, electrical and other industries, tantalum can replace precious metals platinum, so that the cost is greatly reduced. Tantalum is made into a capacitor used in military equipment. America's military industry is developed, and it is the largest arms exporter in the world.
The half of the output of tantalum metal in the world is used in the production of tantalum capacitors, the defense logistics agency is the biggest owner of tantalum metal, once it bought one third of the world's tantalum powder.
