    Bravoite is the name given to a nickel-rich iron sulfide. It is closely related to pyrite but contains up to 20 nickel. Some mineral books treat it as a variety of pyrite. Pyrite is a polymorph of marcasite, which means that it has the same chemistry, FeS2, as marcasite but a different structure and therefore different symmetry and crystal shapes. Pyrite is difficult to distinguish from marcasite when a lack of clear

  • Pyrophoric Nature Of Iron Sulfides Journal Article

    May 01, 1996 Hydrogen sulfide, often present in crude oil tankers, can react with rust to form various sulfides including mackinawite FeS, greigite Fe sub 3S sub 4, and pyrite FeS sub 2. The tendency for these compounds to react with oxygen in air to form potentially explosive mixtures depends upon their morphology and the environmental conditions.
