元素符号Ir，原子序数77。银白色立方晶系金属。不溶于水、酸和碱中，微溶于王水。在空气中加热至800～1000℃时生成氧化铱，更高温时又分解。与硫、磷、卤素在赤热时易发生反应。常与Pt、Os、Au等以伴生矿存在。制法：在镍或铜等电解精制时与铂一起作为副产物的形式而获得。用途：可制热电偶、笔尖、铂铱合金坩埚等。

铱Ir的同位素通常有铱Ir-191，铱Ir-193。

铱Ir的同位素产品介绍

Both Iridium Isotopes, Ir-191 and Ir-193 are used in the production of radioactive material. Ir-191 is used for the production of radioactive Ir-192. This Ir-192 is used as a radiation source in gamma cameras that are used for non-destructive testing. Ir-192 sources are also used in so-called brachytherapy procedures whereby radioactive materials are placed in close contact with the tissue being treated. Although Ir-192 can be produced from natural Ir, the use of enriched Ir-191 gives a much higher specific activity and allows the use of smaller sources. The use of Ir-193 has been suggested for the production of the therapeutic radioisotope Pt-195m.
