Product Description
Introduction
High-purity krypton is a colorless, odorless, non-toxic and stable rare gas. It plays a vital role in many fields. The krypton we provide has a purity of up to 99.999% and extremely low impurity content, ensuring reliability and stability in various applications. Our high-purity krypton is mainly used in the lighting industry, electronics industry, medical field and scientific research field.
Advantages
Extremely high purity
Our high-purity krypton gas can have a purity of more than 99.999%. This means that the impurity content is extremely low, which can ensure reliability and stability in various applications. In some fields that require extremely high gas purity, such as semiconductor manufacturing, scientific research experiments, etc., high-purity krypton gas can avoid impurities from adversely affecting product quality or experimental results.
Stable chemical properties
At normal temperature and pressure, krypton gas hardly reacts chemically with other substances. This allows high-purity krypton gas to maintain its properties during storage and use, without worrying about quality changes caused by chemical reactions.
Non-toxic and harmless:
Krypton gas is a colorless, odorless, non-toxic rare gas that is harmless to the human body and the environment. During use, no harmful substances are produced, ensuring the safety of operators and the sustainability of the environment.

Application
Semiconductor manufacturing:
During the semiconductor manufacturing process, high-purity krypton can be used in plasma etching, thin film deposition and other links. It can provide a stable gas environment to ensure the manufacturing accuracy and quality of semiconductor devices. For example, in the manufacture of integrated circuits, krypton can accurately remove unnecessary materials and realize circuit patterns of tiny sizes.
Medical equipment:
Krypton can also be used in the manufacture of some medical equipment, such as X-ray equipment. Krypton can absorb X-rays and can be used as a shading material when X-rays are working, improving the imaging quality of X-ray equipment.
Special lighting fixtures:
Krypton is also used in special lighting fixtures such as aircraft airport runway lights, off-road vehicle irradiation lights, high-pressure mercury lamps, sodium lamps, zirconium point light sources, flash lamps, and stroboscopic observers. The transmittance of krypton lamps is particularly high, which has advantages in scenes that require strong penetrating lights. For example, the runway needs to provide clear lighting for aircraft takeoff and landing under various weather conditions. Krypton-filled runway lights can meet this demand.
Glass manufacturing industry:
The use of krypton in the glass coating process can form unique properties, such as increasing the hardness of the glass and improving the light transmittance of the glass. For example, in the production of automotive glass and architectural glass, the use of krypton coating can improve the performance of the glass, making it have better heat insulation, sound insulation and UV protection.
Frequently Asked Questions
1. What are the safety precautions for the use of krypton gas?
When using high-purity krypton gas, the following safety precautions should be noted: First, the operator must undergo professional training and be familiar with the properties and safe operating procedures of krypton gas. Secondly, during use, ensure good ventilation to prevent krypton gas accumulation and suffocation hazards. In addition, avoid contact between krypton gas and fire sources to prevent explosions. If krypton gas leaks, emergency measures should be taken immediately, such as closing valves, ventilation, etc., and notify professionals in time for treatment.
2. What are the storage conditions for high-purity krypton gas?
High-purity krypton gas is usually stored in high-pressure cylinders. The storage environment should be kept cool, dry, well ventilated, and away from fire sources, heat sources, and flammable materials. The cylinder should be placed in a fixed position to prevent tipping and collision.
3. What are the applications of high-purity krypton gas in the field of lighting?
In the field of lighting, high-purity krypton gas can be used to fill incandescent bulbs and fluorescent lamps, etc. It can increase the brightness and life of the bulb while reducing the evaporation of the filament. Compared with other filling gases, krypton gas can provide more stable light output and longer service life.
4. What role does high-purity krypton gas play in the electronics industry?
In the electronics industry, high-purity krypton gas can be used in semiconductor manufacturing, flat panel display production and other links. It can be used as an inert gas to provide a stable environment to prevent electronic components from being oxidized and contaminated. In addition, krypton gas can also be used in processes such as plasma etching.
5. Does high-purity krypton gas have any impact on the environment?
High-purity krypton gas itself is a rare gas with very small content in the atmosphere. It is an inert gas and has no direct adverse effect on the environment under normal use. However, during production and use, if leakage occurs, it may cause waste of resources and certain safety risks.
