Iridium metal is a very hard, heavy, rare and expensive silvery material and one of the most noble of all metals. Iridium metal hardly reacts, but as a fine powder indium metal is flammable. Iridium metal is used in special alloys and as a catalyst. Crucibles for high temperature applications are made of pure iridium metal. The meteorite, which 65 million years ago played a key role in the extinction of the dinosaurs, contained relatively much iridium metal. This can still be observed in sediment layers from this time.
