Isoferroplatinum

Isoferroplatinum is an IMA-recognized mineral species in the native element class, with the chemical formula Pt₃Fe.

It crystallizes in the cubic crystal system (space group Pm3m). It is a member of the Perovskite, Auricupride structural group.

Key properties: specific gravity 18.41; Metallic. R: (400) 61.2, (420) 61.2, (440) 61.1, (460) 61.3, (480) 62.3, (500) 63.3, (520) 63.8, (540) 64.3 luster.

IMA symbol Ifpt, IMA status: approved, named in 1974.

Found in Pt–Fe and Cu–Ni sulfide deposits in ultramafic rocks, also in chromatites, and placers derived from them.

It is found associated with Platinum, iridium, osmium, Pt–Fe alloy, braggite, sperrylite, inclusions of many other PGE minerals, gold, pyrite.

The name refers to the cubic (ISOmetric) structure, and iron (FERRum) and PLATINUM in its composition.
