[REEs] The 17 rare earth elements and Uses 17種稀土元素嘅用途

喺17種稀土元素入面，只有少數幾種——特別係釹、鋱同鐠——對製造高性能磁石至關重要。其他元素喺電子、光學同催化方面有唔同嘅用途。

Among the 17 rare earth elements, only a few—especially neodymium, samarium, and dysprosium—are critical for making high-performance magnets. Others serve distinct roles in electronics, optics, and catalysis. Here’s a breakdown of their differences and magnet-related importance:

These five are the magnet superstars. Neodymium leads in strength, while samarium and dysprosium shine in extreme conditions.

Efficiency in Magnet Making Neodymium (Nd) is the most efficient for producing strong magnets. Dysprosium (Dy) is essential for magnets used in high-temperature environments like EV motors. Samarium (Sm) is preferred in aerospace and defense due to its thermal stability.

Pakistan recently sold enriched rare earth elements to the United States, including neodymium, dysprosium, and terbium—key materials for high-performance magnets and clean energy tech. This marks Pakistan’s first-ever REE export under a $500 million strategic partnership. 

 China’s response: Tightened export rules on rare-earth extraction tech, as Pakistan uses Chinese equipment.
