Rare earths are known as industrial “vitamins.” Because of their excellent optical and electromagnetic properties and other physical properties, they can be combined with other materials to form a variety of new materials with a wide variety of properties. Its most significant function is to significantly improve the quality and performance of other products. . For example, the tactical performance of steel, aluminum alloys, magnesium alloys, and titanium alloys used to manufacture tanks, aircraft, and missiles is greatly increased. In addition, rare earths are also a variety of high-tech lubricants such as electronics, lasers, the nuclear industry, and superconductors. Once rare earth technology is used in military, it will inevitably bring about a jump in military technology. In a certain sense, the U.S. military’s overwhelming control in several local wars after the Cold War and its ability to openly kill its enemies’ unscrupulous locality are the result of superhuman technology in the field of rare earth technology.
