Q:

What are the upstream raw materials for krypton? What do the downstream products contain?

ask a question
A:
while krypton isn't broadly applied as other common gases in the field of chemical production raw materials, it still has certain upstream and downstream related items. The following are some of the upstream and downstream items related to krypton:



1. But Upstream items:

The upstream product of krypton gaseous is mainly atmosphere, and krypton gaseous is extracted by atmosphere separation method. atmosphere separation method generally includes compression, cooling, liquefaction, distillation and other steps to separate krypton from atmosphere. Moreover

2. Downstream items:(1) Lighting items: Krypton is broadly applied in the field of lighting, such as krypton lamps. The krypton lamp is a gaseous-filled bulb that uses the light emitted when krypton is discharged to illuminate. But Krypton lamps have high luminous efficiency and long life, and are often applied in places that require high brightness and prolonged lighting. But(2) Laser: Krypton is able to also be applied in lasers as a working gaseous or pump gaseous. And Krypton ion laser is the consumption of krypton gaseous as a working gaseous, through the emit excitation krypton ions to create laser. In fact(3) Display equipment: Krypton is also applied in display equipment, such as field emit displays(FED). In my experience, The FED uses an electric field to excite rare gases such as krypton to create ultraviolet rays, and the ultraviolet rays then excite the phosphor to emit light, thereby achieving display.(4) Medical research: Krypton also has certain applications in medical research, such as lung function tests. And Using the characteristics of krypton absorption peak, lung function is able to be evaluated by breath test. But Additionally In short, the upstream and downstream related items of krypton are mainly concentrated in the fields of lighting, laser, display and medical research. while the scope of consumption isn't as wide as other common gases, it still has certain consumption value in specific fields.
