Robert Wilhelm Eberhard Bunsen
Formula:
NiO
System:
Isometric
Colour:
Dark pistachio-green
Lustre:
Vitreous

Member of:
Name:
Named by James Dwight Dana in 1868 after Robert Wilhelm Eberhard Bunsen (30 March 1811, Göttingen, Germany - 16 August 1899, Heidelberg, Germany), Professor of Chemistry, Heidelberg, who earlier observed artifical crystals of the material. Bunsen investigated emission spectra of heated elements, and co-discovered caesium and rubidium. The well known Bunsen burner is named after him.
Periclase Group.

A rare nickel oxide.
