Niobium Selenide (NbSe2)-Pellets

Characteristic

Niobium diselenide or niobium(IV) selenide is a layered transition metal dichalcogenide with formula NbSe₂. 

Chemical formula：NbSe₂

Molar mass：250.83 g/mol

Appearance：Gray solid

Density：6.3 g/cm³

Melting point：>1300 °C

Crystal structure：hP6, space group

Application

Bemol Incorporated manufactured niobium diselenide in the United States for use as a conducting lubricant in vacuum, as it has a wide temperature stability range, very low outgassing, and lower resistance than graphite. NbSe2 was used as motor brushes, or embedded in silver to make a self lubricating surface.
