The sophisticated weapons on China rare earth

At present, some of the most critical components of modern military hardware America depend entirely on the China rare earth. Laser and magnet world's most advanced weapon system in use is the rare earth metals from Chinese. For example, neodymium magnets are used to produce small missile fin system, smart bombs and satellite system, also used for hybrid power engine equipment production of naval ships in the magnet. Samarium element and cobalt mixed together, to tanks and “ aegis ” manufacturing level of ship navigation system. Ytterbium element is used in the manufacture of tanks and missile laser guidance system.

Although rare earth reserves Chinese accounted for 36% of the global total, but American reserves also many, holds 13% of global reserves, ranking the second place. However, USA found, its rivals are strict control of rare earth resources development of military need it.

In the past 10-20 years, need to USA sophisticated military system of raw materials and finished products can provide for oneself. But, then, main problems America producers is the home for commercial development, concentration of rare earth deposits can be very difficult to obtain. The rare earth elements made of metal and cause high-tech parts costs rising, so that the rare earth mining from USA to China.

Affected by the restrictions on exports of rare-earth minerals China, America Congress in 2010 September through the "revitalize the rare earth and key resources act", aims to promote re manufacturers domestic rare earth development and support local. After America, house and Senate passed the bill more. American hopes to promote American rare earth industry reconstruction has competitiveness through legislative means. America rare earth molybdenum company established suppliers (MolycorpInc. ) announced a few days ago, by the end of 2012, it is located in California rare earth mine annual production capacity increased to 20000 tons. The company also American Department of energy to apply for a loan.

However, American to revive the rare earth industry is not a cold day. America Congress's Government Accountability Office said in a statement, the establishment of a supply chain requires 15 years. And within a short period of time, American home can not be formed in refining and production of high-tech military hardware required magnets and other parts of the rare earth ability.
