Rare earths are known as "industrial vitamins" because of their wide range of uses and important roles in modern industry. Rare earth elements have unique chemical and physical properties, such as rich magnetic, electrical, and optical properties, stable chemical properties, etc., which make them indispensable elements in many high-tech fields.
In electronics, communications, aviation, aerospace, military and other fields, rare earth elements play an important role. For example, in the electronics industry, rare earth elements are widely used in display panels, lasers, magnetic materials and other fields, and their special physical and chemical properties make electronic products have higher performance and better stability. Rare earth elements also play an important role in aviation and aerospace, such as in the manufacture of high-performance engines, satellites and other high-end equipment.
In addition, rare earth elements also have some special properties, such as luminescence, catalysis, etc., which make them have a wide range of application prospects in scientific research and high-tech industries. For example, rare earth elements can be used to make high-efficiency light sources, displays, lasers, etc., as well as catalysts, pharmaceuticals and other fields.
Therefore, due to the wide application and important role of rare earth elements in modern industry, they are figuratively called "industrial vitamins", which means that they are indispensable and important elements in modern industry.
