Holmium Metal (Ho)-Sputtering Target

Characteristic

Holmium is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare-earth element.

Phase at STP： solid

Melting point： 1734 K (1461 °C, 2662 °F)

Boiling point： 2873 K (2600 °C, 4712 °F)

Density (near r.t.)： 8.79 g/cm³

when liquid (at m.p.)： 8.34 g/cm³

Heat of fusion： 17.0 kJ/mol

Heat of vaporization： 251 kJ/mol

Molar heat capacity： 27.15 J/(mol·K)

Application

Holmium has the highest magnetic permeability of any element and therefore is used for the polepieces of the strongest static magnets. Because holmium strongly absorbs neutrons, it is also used as a burnable poison in nuclear reactors.
