Innovative technology upgrade, the rapid development of rare earth industry just around the corner

Rare earth permanent magnet materials are widely used in electric vehicles , wind power, hard disk drives , magnetic resonance imaging , satellite, spacecraft, communications , high- precision machining equipment, and other high-tech industries and fields, is China's response to fog and haze , improve air quality , and actively promote the key material for sustainable development.

Rare earth permanent magnet materials is the largest field of rare earth amount of rare earth new materials accounted for over 60% of amount . "Decision of the State Council on accelerating the cultivation and development of strategic emerging industries ", the proposed development of seven strategic emerging industries, which are associated with rare earth permanent magnet materials are directly or indirectly related , where " rare earth functional materials ." been explicitly included in paragraph ( f) of the " new materials industry ." In recent years , China's rare earth permanent magnet industry technology and scale have made ​​considerable progress . China's rare earth permanent magnet materials in 2012 production reached 80,000 tons , more than 85% of world production, the world's largest production base of rare earth permanent magnet materials .

The rapid development of rare earth materials industry to draw attention to the excessive use of rare earth resources generated concerns national science and technology key special expert group rare earth permanent magnet materials , Steel Research Institute deputy chief engineer , Professor Li Wei rare earth permanent research director , said : " scarcity of rare earth elements in a variety of different rare earth resources , and the most missing is the heavy rare earth elements , as well as a large number of applications due to the relative lack of rare earth permanent magnet materials, raw materials resulting from neodymium , and many other high abundance of rare earth resources such as lanthanum, cerium , as underutilized and idle waste. "

Steel Research Institute with the support of National 863 Program and other projects aimed at the under "rare earth permanent magnet industry Preparation and application of high performance sintered technology" to carry out basic research work related to the development and new composite magnets , explore with Chinese characteristics industrial technology , such as self-developed control technology organizations rare earth permanent magnet materials , hypoxia control technology, balancing the use of technology of rare earth , hot / hot short flow rheology magnet , near -net-shape technology, are in the world. New technology to expand the lanthanum , cerium high REE abundances range of applications , reducing the neodymium , dysprosium, terbium , etc. The amount of rare earth elements , China's rare earth resources can obtain more fully utilized, can generate billions of dollars annually output , is a successful example of the use of rare earth resources in balance . The project has passed the Ministry of Science and acceptance. Related technical cooperation projects with the transfer of the patent by way of radiation main business sectors , led to the development of rare earth permanent magnet industry .

However, at the end of October 2013 held in China Rare Earth Forum , the industry believes that the current development of China's rare earth industry show " mixed " situation. Experts suggest that future policy makers still need to promote the efficient development and intensive use of rare earth resources , to promote resource advantages into economic advantages . Vice President of China Nonferrous Metals Industry Association, Wang Qin believes that the rare earth industry is undergoing profound changes , the future of the rare earth industry policy should focus on rare earths management mechanism , cultivate high-end application market , for light and heavy rare earths category management , foster competition in the industry to improve force , rational distribution, promote the transformation and upgrading of industrial structure adjustment and five considerations.

"Let no mixed rare earth industry , promoting technological innovation and upgrading , to solve common technology industry is our duty . " Li Wei said . It is understood that the results of their research group Li Wei has been developed for the " Shenzhou" series spacecraft, national key project , " Chang E " lunar exploration projects, and new energy vehicles , nuclear power, wind power and other high-tech industries , to meet the higher the evolving requirements of emerging industries of rare earth permanent magnet materials presented .
