The Japanese enterprise alliance wants to speed up the development of rare earth free motors to get rid of the dependence on rare earths in China.

usually, neodymium, which can improve magnetism, dysprosium and other rare earth elements, which can improve heat resistance, need to be added to the magnets used in high-performance motors of Hybrid Electric vehicles and air conditioners. Toyota Motor and Mitsubishi Electric will start to develop new magnets that do not use rare earths for motors used in hybrid electric vehicles and energy-saving household appliances, and strive to achieve industrialization in 2021

although the Ministry of economy, industry and trade of Japan said that the dispute between China and Japan over the Diaoyu Islands has not yet had a great impact on Japan's rare earth procurement, Japan seems to have made up its mind to speed up its dependence on China's rare earth resources

on October 10, Nikkei reported in Chinese that Toyota Motor and Mitsubishi Electric will start to develop new magnets that do not use rare earths for motors used in hybrid electric vehicles and energy-saving household appliances. They plan to establish a high-efficiency magnetic material technology research alliance for motors in the middle of this month, and strive to achieve industrialization in 2021. The Ministry of economy, industry and trade of Japan will provide support for the research by issuing R & D subsidies and issuing preferential policies

it is reported that 11 Japanese enterprises and groups, including Daikin industry, electrical equipment, Aichi steel and NEC Dongjin, participated in the research alliance of magnetic materials technology for high-efficiency motors this time

in general, rare earth elements such as neodymium, which can improve magnetism, and dysprosium, which can improve heat resistance, need to be added to magnets used in hybrid electric vehicles and high-performance motors of air conditioners. According to the above report, through academic research, new magnets made by mixing other metals into iron can theoretically be more magnetic than neodymium magnets

for a long time, Japan has been China's most stable and largest rare earth export market, but it has almost never stopped trying to get rid of its dependence on China's rare earth. At present, most of the rare earth resources that Japan obtains from other channels are light rare earth such as neodymium and cerium (which can ensure 60-80% of Japan's domestic demand). Although the overall dependence of its rare earth on China has dropped to less than 50% after the end of the experiment, Japan's dependence on China is still more than 90% for heavy rare earth such as dysprosium

for a long time, medium heavy rare earth has been a specialty of China. Chenzhanheng, Deputy Secretary General of China Rare Earth Industry Association, told the morning post yesterday that Japan's move cannot be said to be aimed at China in particular. Dysprosium itself is not enough and does not support the long-term use of human beings. At present, there is no exact data on how long the proved reserves can be used

Japan's goal: the self-sufficiency rate of rare earths will reach 50% by 2030.

. However, this response has not been echoed by the Chinese authorities. Subsequently, on October 1st, 2010, Japan, including integrated robots and molds, immediately announced that in order to get rid of the heavy dependence on China for rare earth import, it would implement the plan to develop rare earth alternative materials in advance, and prepare to develop rare earth in more countries to achieve multi-channel supply of rare earth

according to the report of the Japanese Economic Journal quoted by the Chinese Ministry of Commerce, Japan has expanded the import of rare earth metals outside China in various ways. In the first half of this year, Japan imported 3007 tons of rare earth metals from China, accounting for 49.3%, which fell below 50% for the first time since 2000. Before 2009, more than 90% of Japan's rare earth resources needed to be imported from China

the Japanese economy previously said that Japan has ensured a total of about 16500 tons of rare earth metal mine resources in Australia, Kazakhstan, India, Vietnam and other countries. It is expected that these countries can start exporting to Japan in 2013

in terms of dysprosium and other heavy rare earths, Japanese enterprises such as Toyota Tsusho are increasing their efforts to acquire dysprosium. They are jointly developing heavy rare earth mines in Canada with local enterprises. It is expected that dysprosium can be supplied to Japan from 2015

Japan aims to increase the self-sufficiency rate supported by Japanese enterprises' overseas rare earth mine interests and domestic rare earth recovery to 50% by 2030

in fact, not only Japan, but also China is preparing for the limited rare earth resources. According to the white paper "China's rare earth status and policies", the state promotes the balanced utilization of rare earth elements, encourages the application research of relatively rich light rare earth elements such as lanthanum and cerium, and speeds up the development of reduction and substitution technologies for rare heavy rare earth elements such as europium, terbium and dysprosium

Japan's chips and China's advantages

Japan has always been cautious about China's rare earth trade

Hongfeng, former director of the office of the national rare earth working group, once told the morning post that before China's rare earth market was fully opened, Japan mainly imported rare earth ore raw materials and semi-finished products from the United States and Australia for further processing, and also imported some fine processed rare earth products from France and other places. Japan has been somewhat uneasy about importing China's rare earth minerals (including ionic rare earth minerals rich in medium and heavy rare earths)

some people believe that Japan believes that China wants to obtain Japan's rare earth application technology, especially advanced application technology, through China Japan rare earth trade cooperation

the advantages of China's rare earth industry are still in the smelting process. In 2011, the output of rare earth smelting products in China was 96900 tons, accounting for more than 90% of the world's total output. However, deep processing is still in its infancy

our functional material industry used to be very small. The accelerated development after 2004 is mainly due to the investment of foreign enterprises in China after China's accession to the WTO. Chenzhanheng said that the Japanese rely on technology for food and will try their best to extend the validity of their patents

for example, he said that just last month, at the request of Hitachi metal and its U.S. subsidiaries, the U.S. International Trade Commission launched 337 investigations on more than 20 enterprises to determine whether these enterprises had patent infringement against the enterprise, including four Chinese rare earth enterprises. The profitability of China's paper industry showed a trend of improvement. Zhenghai magnetic materials was among them
