ガスの説明
Xenon gas is a colorless, odorless, non combustible inert compressed gas with a content of 90ppm in air. Xenon gas is mainly used in flash lamps, deep anesthetics, lasers, welding, refractory metal cutting, standard gas, special mixed gas, etc. Krypton xenon gas mixture filled electronic tubes and bulbs can save 20-25% of electricity compared to argon bulbs of the same power, prolong their lifespan by 2-3 times, increase their luminous efficiency, and greatly reduce their volume. Xenon gas has extremely high light emission intensity, and lamps filled with xenon gas include iodine lamps, arc lamps, flash lamps, cinema projection lamps, space simulation lamps, etc. Xenon gas is a high-pressure xenon arc discharge lamp developed in 1958, which is divided into long arc xenon lamps, short arc xenon lamps, and pulse xenon lamps. The long arc xenon lamp filled with xenon gas has a spectrum very close to sunlight, commonly known as "Little Sun". This type of xenon gas lamp has a particularly strong ability to penetrate fog and is commonly used for lighting in stations, docks, and squares. The color of the "short arc xenon lamp" is similar to noon sunlight, with a high color temperature (5600K) and convenient use. It is currently an ideal artificial "sun lamp" for square, street, movie screening, and stage lighting. Pulse xenon lamp is a light source that emits light in a short period of time, commonly known as a "flash lamp". It uses xenon gas pulse discharge to emit light, and this type of small xenon lamp is widely used in photography. Xenon, as an anesthetic, is highly valued in medicine. Xenon can dissolve in the lipid of the cytoplasm, causing anesthesia and swelling of the cells, thereby temporarily stopping the action of nerve endings. People have tried a mixture of 80% xenon gas and 20% oxygen as an anesthetic with no side effects. In the atomic energy industry, high-purity xenon gas can be used to test the presence of high-speed particles, particles, mesons, etc.
主な用途
High purity xenon gas is widely used in the electronics and electric light source industry. Compared with argon filled bulbs of the same power, xenon filled bulbs have the advantages of high luminous efficiency, small size, long lifespan, and energy saving. Due to its strong fog penetrating ability, it is commonly used as a fog navigation light and is widely used in airports, stations, and docks. After focusing on the concave surface of the xenon lamp, it can generate a high temperature of 2500 ℃ and can be used for welding or cutting refractory metals such as titanium and molybdenum. In medicine, xenon gas is a contrast agent for deep anesthesia X-ray imaging that has no side effects.
High purity xenon gas is used in excimer lasers, light bulbs, ion propulsion, aviation, medical, and experimental research.
Physical and chemical properties: Xenon gas is a chemical element with the symbol Xe and atomic number 54. It is a colorless and odorless rare gas that appears blue when discharged. There are trace amounts of xenon in the Earth's atmosphere. Except for a few compounds, xenon compounds are colorless.
