Krypton gas is a colorless, odorless, and odorless rare gas. Krypton gas is chemically inert, cannot be burned, and does not contribute to combustion. It has low thermal conductivity, high transmittance, and can absorb X-rays.

      Krypton gas can be extracted from the atmosphere, ammonia exhaust or fission gas from nuclear reactors, but is generally extracted from the atmosphere. There are many ways to prepare Krypton gas, the main ones are catalytic reaction, adsorption and low temperature rectification.

      The extraction process of Krypton gas is complicated and difficult, and the production operation procedure is very strict. Krypton gas is generally prepared in two stages: the crude system and the refining system. In the extraction process, special equipment and materials are not only needed for high pressure and low temperature treatment, but also special attention should be paid to safety, explosion protection and leakage prevention.

      Krypton gas has been widely used in lighting filling gas, insulating glass manufacturing and many other industries due to its unique characteristics.
