Why is gadolinium oxide widely used in the metallurgical industry?

Gadolinium oxide is widely used in the metallurgical industry mainly due to its effective role in improving the properties of metal materials. In steel production, as an additive, it can refine the grain. When it is incorporated into molten steel, it can interact with other elements to change the grain growth pattern, making the grains fine and uniform, and thus significantly enhancing the strength and toughness of steel. This is crucial for the production of high-strength construction steel, machinery manufacturing steel and so on. In the production process of non-ferrous metals such as aluminum and magnesium alloys, gadolinium oxide can also play a role in improving the mechanical properties and heat resistance of alloys, meeting the requirements for high strength and stability of aluminum alloys in high-temperature environments in fields like aerospace. In addition, in the production of rare earth permanent magnet materials, as an important raw material, gadolinium oxide, in cooperation with other rare earth elements, can adjust the magnetic properties of materials, improve the stability and high-temperature resistance of permanent magnet materials, and expand its application range in numerous fields such as motors, generators, speakers, and maglev trains.
