Ir

1. Introduce – Iridium is a platinum-group metal with a high melting point and extremely low corrosion susceptibility; it is used as pure iridium or in alloys with other platinum-group metals – It is the most corrosion-resistant of all metallic elements and possesses such high corrosion resistance that it does not dissolve even in strong acids – In its molten state, it reacts with NaCl and NaCN, and at high temperatures, it reacts with halogen elements (F₂, Cl₂) 2. Application & Product – High-temperature compound semiconductors, electrical contacts, chemical cataly...
