Tantalum has a wide range of applications because of its characteristics. Tantalum can be used as a substitute for stainless steel in the equipment for making various inorganic acids, and its service life can be increased dozens of times than that of stainless steel. In addition, in chemical, electronic and electrical industries, tantalum can replace the tasks previously undertaken by precious metal platinum, which greatly reduces the cost. Tantalum is manufactured into capacitive equipment for military use. The U.S. military industry is extremely developed and is the world\'s largest arms exporter. Half of the world\'s tantalum production is used to produce tantalum capacitors. The U.S. Department of Defense Logistics, the largest owner of tantalum, once bought a third of the world\'s tantalum powder.
