FAQ
Rhenium is a chemical element with the symbol Re and CAS number 7440-15-5. It is a rare, silvery-white transition metal with a high melting point. Rhenium is one of the rarest elements in the Earth's crust and is used in various high-temperature applications and catalysts.
Rhenium is primarily used in high-temperature alloys, superalloys, and filaments for X-ray tubes. It is also used in catalysis, particularly in the production of gasoline from heavy petroleum fractions. Additionally, it is used in electronic and medical applications.
Rhenium itself is generally considered safe, but handling should be done with care. It can cause skin and eye irritation if inhaled or contacted. Protective measures include wearing gloves, goggles, and protective clothing. Storage and handling should be in a well-ventilated area away from heat and sparks.
Rhenium should be stored in a cool, dry, and well-ventilated area away from heat, sparks, and oxidizing agents. It should be kept in a tightly sealed container to prevent oxidation. Exposure to air can cause rhenium to oxidize, especially at higher temperatures.
