A common analogy is, if the oil is the blood of industry, it is the rare earth industry vitamin.
Rare earth is referred to as a group of metal and contains a periodic table of the Chemical Elements Lanthanum, cerium, praseodymium, 17 kinds of elements, has been widely used in many fields of electronics, petrochemical, metallurgy and so on. Almost every 3-5 years, scientists will be able to find rare earth new uses, every six invention, a can not be separated from rare earth.
China rare earth mineral rich, dominating the worlds first reserves: first, the scale of production, exports. At the same time, China is the only one capable of providing all 17 rare earth metals, especially military uses an extremely prominent heavy rare earth, China occupies the share of people envy.
Rare earth is precious strategic resources, "industrial monosodium glutamate" and mother of the new materials, "said, is widely used in the field of cutting-edge technology and military areas. According to the Ministry of industry and information technology, at present rare earth permanent magnetism, luminescence, hydrogen storage and catalysis functional materials is advanced equipment manufacturing industry of new and high technology industry, new energy, and other emerging industries indispensable raw material, is widely used in electronics, petroleum, chemical, metallurgy, machinery, new energy, light industry, environmental protection, agriculture and so on.
As early as 1983, Japan issued a rare strategic mineral resources reserve system, its 83% domestic rare earth from China. What is worth mentioning is that there have been media reports, Japan bought in a large number of rare earth, not in a hurry to use, but will exist on the ocean floor, to respond to future energy needs.
In the United States and its rare earth reserves second only to China, but its beginning in 1999, take storage means phasing out its rare earth resources exploitation, which, in turn, from China to import large quantities.
Comrade Deng Xiaoping once said: "there is oil in the Middle East, Chinese with rare earth." His words had overtones of self-evident. Rare earth is not only the world one-fifth of the high-tech products necessary "MSG", it is the future of China in the world on the table a powerful cards chips. Protection and scientific use of rare earth resources, not to let the precious rare earth resources blindly cheap exports to western countries, has become in recent years a number of people with lofty ideals called for a national strategy. Deng Xiaoping in 1992 explains that China rare earth superpower. 97% of the world's supply of rare earths from China, Western fears of excessive dependence on Chinese rare earth resources. But rare is the Chinese resources, have the right to dispose of China, no need to care and dissatisfaction.
