Thulium (Tm) Metal

HTRE908

New product

Thulium is a silver-white metal, ductile, soft, and can be cut with a knife; the melting point is 1545°C, the boiling point is 1947°C, and the density is 9.3208.
Thulium is relatively stable in the air; thulium oxide is a pale green crystal. Silver-white metal, soft in nature, has a high vapor pressure at the melting point. Salt (divalent salt) oxides are light green.
