Bunsenite

This page is currently not sponsored. Click here to sponsor this page.
Robert Wilhelm Eberhard Bunsen
Formula:
NiO
Colour:
Dark pistachio-green
Lustre:
Vitreous
Hardness:
Specific Gravity:
6.898
Crystal System:
Isometric
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 artificial crystals of the material. Bunsen investigated emission spectra of heated elements and co-discovered cesium and rubidium. The well known Bunsen burner is named after him.
Periclase Group.

A rare nickel oxide.
