Iridium (Lat. Iridium) is one of the rarest metals on Earth. It is known for its high corrosion resistance and excellent thermal conductivity. Although pure iridium is extremely brittle, combining it with other metals adds strength and durability to the resulting alloys. Iridium has a melting point of 2410°C and a boiling point of 4527°C.
Iridium (chemical symbol Ir) is used in many specialised industries where the element’s resistance to corrosion and high temperatures is crucial. The amounts of iridium found in conventional electronic devices are extremely small. As a result, it wouldn’t be economically viable to process such devices for iridium extraction purposes.
Iridium is used in the manufacture of organic light-emitting diode (OLED) products, such as the screens of modern televisions and computers. It is also selected for the manufacture of specialized containers used in the melting and processing of other industrial metals. Small amounts of iridium are required in the complex manufacturing processes of lithium-ion batteries for electric cars and automotive glow plugs. Along with other platinum group metals, iridium is also widely used in the manufacture of various types of jewellery.
