Iridium is a platinum group metal with atomic number 77. Ir is very hard and brittle metal with silvery color. Iridium has great corrosion resistant even at high temperature as 2000C. Iridium is an ideal material for tip of spark plugs and has been used to make crucible for artificial crystals manufacturing

Materials and description, Crucibles and their covers are made of high temperature-resistant materials, usually porcelain, alumina or an inert metal. One of the earliest uses of platinum was to make crucibles. Ceramics such as alumina, zirconia, and especially magnesia will tolerate the highest temperatures. More recently, metals such as nickel and zirconium have been used. The lids are typically loose-fitting to allow gases to escape during heating of a sample inside.
