Although the Ministry of Economy, Trade and Industry said that the Sino-Japanese Diaoyu Islands dispute has not caused much impact on Japan's rare earth procurement, Japan seems to have made up its mind to accelerate the reliance on China's rare earth resources. On October 10, the Nikkei Chinese website reported that Toyota Motor and Mitsubishi Electric will start developing new magnets that do not use rare earths for motors for hybrid vehicles and energy-efficient home appliances. It plans to set up magnetic materials for high-efficiency motors in the middle of this month. Technology Research Alliance" strives to achieve industrialization in 2021. The Ministry of Economy, Trade and Industry of Japan will support research by issuing research and development subsidies and introducing preferential policies. According to reports, 11 Japanese companies and groups such as Daikin Industries, Denso, Aichi Steel and NEC Dongjin participated in the "Innovative Magnetic Materials Technology Research Alliance". In general, in a magnet used in a hybrid vehicle and an air conditioner high-performance motor, it is necessary to add a rare earth element such as "é’•" which can improve magnetic properties and "é•" which can improve heat resistance. According to the above report, through academic research, a new magnet made of iron mixed with other metals can theoretically exceed the neodymium magnet. Japan has long been China's most stable and largest export market for rare earths, but it has almost never stopped concentrating on China's dependence on rare earths. At present, most of the rare earth resources that Japan has obtained from other sources are “light rare earths†such as antimony and antimony (which can ensure 60 to 80% of domestic demand in Japan). Although the dependence on rare earths in China has fallen below 50%, On the “heavy rare earths†such as strontium, Japan’s dependence on China is still over 90%. Medium and heavy rare earths have always been China's "specialties." Chen Zhanheng, deputy secretary general of China Rare Earth Industry Association, told the Morning Post reporter yesterday: "Japan's move cannot be said to be specifically aimed at China. The element itself is not enough. It does not support long-term use of human beings. How long is the proven reserves available? A definitive data." Japan's goal: self-sufficiency rate of rare earths reached 50% in 2030. After the collision of the Diaoyu Islands in September 2010, Chinese people have called on government departments to stop exporting rare earths to Japan. However, this response has not been echoed by the Chinese authorities. Subsequently, on October 1, 2010, the Japanese side immediately announced that in order to get rid of China's rare imports of rare earths, it is necessary to implement plans to develop rare earth substitute materials in advance, and at the same time prepare to develop rare earths in more countries to achieve multi-channel supply of rare earths. According to the report of the Ministry of Commerce of the People's Republic of China, Japan Economic News reported that Japan has expanded its imports of rare earths outside China through various means. In the first half of this year, the total amount of rare earth metals imported from China by Japan was 3,007 tons, accounting for 49.3%. For the first time since 2000, it has fallen below 50%. Before 2009, more than 90% of Japan's rare earth resources need to rely on imports from China. "Nihon Keizai Shimbun" previously said that Japan is currently ensuring a total of about 16,500 tons of rare earth metal mine resources in Australia, Kazakhstan, India, Vietnam and other countries. It is expected that these countries will be able to export to Japan in 2013. In terms of “heavy rare earths†such as bismuth elements, Japanese companies such as Toyota Tsusho are increasing their efforts to jointly develop the country’s “heavy rare earth†mines with local companies in Canada. It is expected to supply yttrium to Japan in 2015. Japan's goal is to increase the “self-sufficiency rate†of Japanese companies' overseas rare earth mine rights and domestic rare earth recovery support to 50% by 2030. In fact, not only Japan, China is also preparing for limited rare earth resources. The White Paper on China's Rare Earth Conditions and Policies shows that the state promotes the balanced use of rare earth elements, encourages the application of relatively abundant light rare earth elements such as lanthanum and cerium, and accelerates the development of rare earth elements such as lanthanum, cerium and lanthanum. Alternative technology. Japanese chips and China's advantage Japan has always been cautious about China's rare earth trade. Hong Feng, former director of the National Rare Earth Working Group Office, told the Morning Post reporter that before China's rare earths did not fully open the export market, Japan mainly imported rare earth mineral raw materials and semi-finished products from the United States and Australia, and further deep-processing itself, also from France and other places. Imported parts of finely processed rare earth products. Japan has been somewhat uneasy about importing rare earth minerals from China, including ionic rare earth minerals rich in medium and heavy rare earths. Some people believe that Japan believes that China wants to acquire rare earth application technology in Japan through the Sino-Japanese rare earth trade cooperation, especially advanced application technology. The advantages of China's rare earth industry are still in the smelting process. In 2011, the output of China's rare earth smelting products was 96,900 tons, accounting for more than 90% of the world's total output. However, the deep processing link is still in its infancy. “Our functional materials industry is very small. The acceleration after 2004 is mainly due to the investment of foreign companies in China after China’s accession to the WTO.†Chen Zhanheng said, “The Japanese are relying on technology to eat and will desperately extend their patents. For example, just last month, the US International Trade Commission initiated a “337 investigation†on more than 20 companies at the request of Hitachi Metals and its US subsidiary to determine whether these companies have patents for the company. Infringement, involving 4 Chinese rare earth enterprises, Zhenghai magnetic materials are among them.
