Iron Disulfide, FeS2 (Pyrite)
Categories: Ceramic; Sulfide/Chalcogenide

Material Notes: Pyrite crystals are known as "fool's gold" because of their shiny golden appearance; Iron Disulfide may also appear tarnished. Weathering end product: Limonite . Occurrence: Common in all rocks. SO2 ion released during weathering, which may oxidize to SO3. Expands during oxidation and hydration to limonite.

Key Words: FeS2, Iron Disulfide
