FAQ

What is Iridium (CAS: 7439-88-5)?

Iridium (CAS: 7439-88-5) is a chemical element with the symbol Ir and atomic number 77. It is a lustrous, hard, brittle, and corrosion-resistant transition metal with a silver appearance. Iridium is one of the densest elements and is a member of the platinum group metals.

What are the main uses of Iridium (CAS: 7439-88-5)?

Iridium (CAS: 7439-88-5) is primarily used in the production of high-strength alloys, electrical contacts, and wear-resistant parts. It is also used in platinum-iridium alloys for standard measurement instruments, spark plugs, and electrodes. Additionally, iridium is used in the catalyst industry and as a component in some specialized batteries.

Is Iridium (CAS: 7439-88-5) safe?

Iridium (CAS: 7439-88-5) is generally considered safe for industrial use when proper handling procedures are followed. However, it is corrosive and can release toxic fumes when heated or exposed to water. Protective gloves, goggles, and respiratory equipment are recommended to prevent inhalation of dust and fumes.

How should Iridium (CAS: 7439-88-5) be stored?

Iridium (CAS: 7439-88-5) should be stored in a cool, dry place away from direct sunlight and moisture to prevent corrosion. It should be kept in a sealed container made of a compatible material, such as stainless steel, and stored in a well-ventilated area to avoid the formation of toxic fumes. Avoid exposure to acids and other corrosive substances.
