Named in 1995 by Martin R. Lee, Sara S. Russell, John W. Arden, and C.T. Pillinger in honor of Alfred Otto Carl Nier (May 28, 1911 – May 16, 1994), physicist and Professor of Chemistry at the University of Minnesota, Minneapolis, Minnesota, USA. He was responsible for the now accepted measurement of the atmospheric N-isotope composition. Also was instrumental in the development of mass spectrometry (especially stable isotope mass spectroscopy).

Type Locality:

ⓘ Indarch meteorite, Hindarx, Aghjabadi District, Azerbaijan

Dimorph of:

UM1995-14-N:Si

A very rare natural nitride, originally formed in star dust and now found in meteorites.

Synthetic silicon nitride is a very important high-performance ceramic.
