Introduction of Rare Earth Uses -

China Rare Earth Resources

Japan is the main country that needs to use rare earth, currently the quantity of Chinese exports of rare earth ranks first in the world. As the key materials of a number of major weapons systems, rare earth in America almost all needs to import from China. Rare earth is the richest strategic resource of China, it is the raw material essential for many highly sophisticated industry, China has a lot of strategic resources are in a shortage state, such as iron ore and other elements, but very rich in rare earth resources. Currently, resources are valuable wealth of a country, but also an important weapon for developing countries to safeguard their own interests and against major powers might. Comrade Deng Xiaoping, the chief architect of China's reform and opening up once eloquently once said: "Middle East has rich oil resources, and we have rich rare earth resources." China's largest rare earth manufacturer announced the discontinuation for a month, in order to support the declining price of rare earth, which is by far the clearest signal that the intention that the rare earth mining companies in China are to maintain the high price of rare earth.

Rare Earths and Military

The rare earth is also known as the industry "gold", due to its excellent optical and electromagnetic physical characteristics, the performance of different composition and other materials, a wide variety of new materials, the most significant function is to greatly improve the quality and performance of the other products. Such as cerium oxide used in the manufacture of tanks, aircraft, missiles, steel, aluminum, magnesium alloys, titanium and tactical performance is greatly improved. Moreover, the earth can be used as many other high-tech lubricants such as electronics, laser, nuclear industry, and superconducting. So, a lot of cerium oxide producer always want to maintain the high price of rare earth. The rare earth technology once used for military, it will inevitably bring about a leap in military technology. In a certain sense, said several local wars, the U.S. military in the post-Cold War overwhelming control, and unbridled public enemy killing, is due to the superior rare earth science and technology.

Rare Earth and Metallurgical Industry

If the rare earth metal or fluorides, silicides are added to the steel, they can play the role of the refining, desulfurization, and low melting harmful impurities, and can improve the workability of the steel; producing rare earth rare earth ferrosilicon alloy, rare earth the attapulgite alloy as nodulizer Ductile Iron, Ductile Iron is especially suitable for the production of the special requirements of complex nodular iron castings, is widely used in automobiles, tractors, diesel engines and other machinery manufacturing; rare earth metals magnesium, aluminum, copper, zinc, nickel and other nonferrous if added to alloy, it can improve the physical and chemical properties of the alloy, and improve the alloy mechanical properties at room temperature and high temperature.
