WebYttrium is a silver-metallic, lustrous rare earth metal that is relatively stable in air and chemically resembles the lanthanides. Shavings or turnings of the metal can ignite in air when they exceed 400 ° C. When yttrium is finely divided it is very unstable in air. The metal has a low neutron cross-section for nuclear capture.
