Rare Earth is a strategic metal that is related to world peace and national security. Why the "Patriot" missiles can be relatively easily destroyed "Scud" missiles? This is due to the former excellent precision guidance system work. Its guidance system uses about 4 kg of samarium cobalt magnets and neodymium iron boron magnets for electron beam focusing, samarium and neodymium are rare earth elements.
Why M1 tanks can be the first to find? Because the tank equipped with neodymium-doped yttrium aluminum garnet laser range finder, in the clear day can reach nearly 4000 meters viewing distance, and T-72 laser ranging machine can see To 2000 meters even if not bad. In the nighttime, night-vision devices that incorporate lanthanum rare earth elements have become the nightmare of the Iraqi army.
As for the F-22 supersonic cruise function, thanks to its powerful engine and light body thanks to a solid, they make extensive use of rare earth technology to create special materials. For example, F119 engine blades and combustion chamber using a flame-retardant titanium alloy, the manufacture of this titanium alloy is said to use rhenium; and F-22 fuselage is even more with rare earth-enhanced magnesium titanium alloy.
Rare earth has the industrial "gold", because of its excellent physical properties of the photoelectric magnet, with other materials with different properties, a wide variety of new materials, the most significant function is to significantly improve the quality and performance of other products . For example, a substantial increase in the manufacture of tanks, aircraft, missiles steel, aluminum, magnesium alloy, titanium alloy tactical performance. Moreover, rare earth is also the electronics, laser, nuclear industry, superconductivity and many other high-tech lubricants. Once used in the military, rare earth science and technology will surely bring about a leap in military science and technology.
