DuPontâ¢ Krytox Â® oils and greases are high-performance perfluorinated lubricants used for a variety of applications. Used where temperatures commonly exceed 250Â°F or fall below 0Â°F.
Krypton, like the other noble gases, is used in lighting and photography. Krypton light has many spectral lines, and krypton plasma is useful in bright, high-powered gas lasers (krypton ion and excimer lasers), each of which resonates and amplifies a single spectral line. Krypton fluoride also makes a useful laser.
