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.
High Purity Iridium Metal small crystals 99.99% pure, the sample weighs 0.1 gram approx. it is placed in labeled glass vial. Pure Iridium metal for element collection and laboratory.
Sensational Iridium metal standard density cube 10x10x10mm, 99.99% pure. The sample weighs 22.60 grams (with a tolerance of ± 0.1gram), which is the theoretical density of the Iridium metal itself. This cube is amazing for any science classrooms, schools, universities and collectors. Pure Iridium metal cube for element collection.
