Iridium is a very hard and brittle, silvery metallic transition element. It has a yellowish cast to it. Salts of iridium are highly colored. It is the most corrosion resistant metal known, not attacked by any acid, but is attacked by molten salts. There are 2 natural stable isotopes of iridium. Totally iridium has 39 isotopes. The most stable being Ir-192 with a half-life of 73.83 days. Ir-192 decays into Platinum, while some radioisotopes decay into Osmium. Iridium is used in high temperature apparatus, electrical contacts. Iridium was discovered by Smithson Tennant in England in 1803. The name Iridium comes from the Greek word Iris, which means rainbow. Iridium metal is generally non-toxic due to its relative unreactivity, but iridium compounds should be considered highly toxic.
Iridium is used with osmium to tip gold pen points, to make crucible and special containers. It is used also to make alloys applied for standard weights and measures, and heat-resistant alloys. Iridium is used as hardening agent for platinum too.
