Rare earths are called "gold" and "vitamins" in industry. Because of its excellent physical properties such as optoelectromagnetism, it can be combined with other materials to form new materials with different properties and varieties. Its most significant function is to greatly improve the quality and performance of other products. For example, the tactical performance of steel, aluminum alloy, magnesium alloy and titanium alloy used to manufacture tanks, planes and missiles will be greatly improved. Moreover, rare earth is also a lubricant for electronics, lasers, nuclear industry, superconductivity and many other high technologies.
From 65438 to 0987, rare earths were used in computer production and other electronic products. Then, rare earths are widely used in many high-tech industries, from wind turbines to missiles, mobile phones, lighting, and especially rare earths are very important for clean energy technology. Rare earth is one of the core materials of clean energy industry, even involving military high-tech and other national security core departments, which is related to strategic competition between countries.
In order to ensure the normal operation of the national defense economy in wartime, Japan has established a huge civil and strategic energy reserve. Japan's strategic oil reserves reach 16 1 day, which is "very safe" by international standards. Japan has established a domestic reserve of rare metals for 60 days, including 42 days for the state and 0/8 days for the people. Mainly rare metals such as nickel, chromium, tungsten, cobalt, molybdenum, vanadium, manganese, etc., and the dependence on imports exceeds 90%.
Japan's Protection and Utilization of Rare Earth
1, Rare Earth Reserve: Japan implements a rare earth reserve system to ensure the country's demand for rare earths by purchasing and storing rare earth resources.
2. Technology research and development: Japan strengthens the research and development of rare earth technology, improves the level of rare earth processing technology and added value of products, and reduces its dependence on rare earth resources.
3. Environmental protection measures: In the process of rare earth mining and processing, Japan has taken environmental protection measures to reduce the impact on the environment.
4. Cooperation with other countries: Japan cooperates with other countries to develop and utilize rare earth resources to ensure the stability of global rare earth supply.
