Melting point: 2784 F
Boiling point: 5194 F
Common oxidation state: Solid
Other properties: Soft, Shows some pink coloring.
Erbium have very little use as a metal because it slowly tarnishes in the air and is attacked with water. Erbium can be found in monazite and bastnaesite.
Erbium is mainly produced in China, Russia and Malaysia.
