Description

Most of the world's terbium disappears into green phosphors and heat-resistant neodymium magnets, so solid chunks of it are an uncommon sight. The metal is silvery-gray and soft enough to cut with a knife. It stores well when kept dry and ships heat-sealed to protect it from moisture.

Specs: • Purity: 99.9% (3N) • Form: chunks • Packaging: sealed bag, moisture-free • Origin: Kazakhstan
