Uakitite
A vanadium nitride known only from the single Uakit meteorite that fell in Buryatia, Russia.
Intro adapted from Wikipedia (CC BY-SA).
Uakitite is an IMA-recognized mineral species in the native element class, with the chemical formula VN.
It crystallizes in the cubic crystal system (space group Fm-3m). It is a member of the Rocksalt structural group.
Key properties: Mohs hardness 9–10; specific gravity 6.128; White streak; Metallic luster.
IMA symbol Uak, IMA status: approved, named in 2018.
An accessory phase in an iron meteorite. Formed due to high-temperature (>1000 flC) separation of Fe-Cr-rich sulfide liquid from Fe-metal melt.
It is found associated with In troilite-daubréelite (±schreibersite) inclusions (to 100 µm) and in troilite-daubréelite nodules (to 1 cm) in Fe-Ni-metal (kamacite).
The name refers to the Uakit iron meteorite.
