About Scandium
Scandium is a soft, silvery-white transition metal often classified as a rare earth element. It develops a yellowish tinge when oxidized. Scandium is common in stars but rare on Earth in concentrated deposits.
Gebruiks & Programme
Aluminum-scandium alloys for aerospace, sports equipment, and high-intensity metal halide lamps.
Fun Fact
Scandium is so dispersed in Earth's crust that concentrated deposits are rare, making it more expensive than most rare earth elements.
