Formula:
(Ru,Os,Ir,)5(Fe,Cr,Ni)6
author's formula: (Ru,Os,Ir,Pt)0.40-0.45(Fe,Ni,Cr)0.52-0.60
Crystal System:
Hexagonal
Although somewhat chemically similar to hexaferrum, this seems to be the first natural Ru-Fe alloy (or intermetallide) to date.
One of a few PGMs from alpine-type chromitites derived from two peridotites. The alloy is porous and forms 3-30 micron sized individuals.
