Praseodymium (Pr): The Green Twin
Named after the Greek words prasios didymos ("green twin"), Praseodymium was first isolated in 1885 by Carl Auer von Welsbach. Known for its distinct green hue, it is vital in creating strong, lightweight alloys for aircraft engines. Praseodymium is also used in powerful permanent magnets, green coloring for glass and ceramics, and in specialized optical filters. Its strategic value lies in its role in high-tech manufacturing, from clean energy to aerospace applications.
