Krypton is a colorless, tasteless, and odorless rare gas. Krypton is chemically inactive, cannot burn, and does not support combustion. It has low thermal conductivity, high transmittance, and can absorb X-rays.
Krypton can be extracted from the atmosphere, synthetic ammonia tail gas, or nuclear reactor fission gas, but it is generally extracted from the atmosphere. There are many methods for preparing krypton, and the commonly used methods are catalytic reaction, adsorption, and low-temperature distillation.
Krypton is widely used in lighting lamp filling gas, hollow glass manufacturing, and other industries due to its unique characteristics.
Lighting is the main use of krypton. Krypton can be used to fill advanced electronic tubes, continuous ultraviolet lamps for laboratories, etc.; krypton lamps save electricity, have a long service life, high luminous efficiency, and small size. For example, long-life krypton lamps are important light sources for mines. Krypton has a large molecular weight, which can reduce the evaporation of the filament and extend the life of the bulb. Krypton lamps have a high transmittance and can be used as runway lights for aircraft; krypton can also be used in high-pressure mercury lamps, flash lamps, stroboscopic observers, voltage tubes, etc.
Krypton gas also plays an important role in scientific research and medical treatment. Krypton gas can be used to fill ionization chambers to measure high-energy rays (cosmic rays). It can also be used as light-shielding materials, gas lasers, and plasma streams during X-ray operation. Liquid krypton can be used in the bubble chamber of particle detectors. Krypton’s radioactive isotopes can also be used as tracers in medical applications.
