About Perryite
Stuart H. Perry
Formula:
(Ni,Fe)5(Si,P)2
also given as (Ni,Fe)16PSi5 (from structure solution)
Colour:
Silver-white
Crystal System:
Trigonal
Name:
Named in honor of Stuart Hoffman Perry (13 October 1874, Pontiac, Michigan, USA - 14 February 1957, Tucson, Arizona, USA), newspaper publisher and authority on meteorites.
Type Locality:
A meteoric mineral.
Recent crystal structure solution, based on Mount Egerton aubrite material, shows it to be the first example of P-Si ordering in natural phosphide-silicide.
