Application of xenon in medical industry

The medical sector offers new long-term potential growth for xenon applications. Xenon is used to enhance the imaging of X-rays, CAT scans, and MRI. A single MRI device cannot examine many fine structures in the human lung, however, by inhaling the xenon/oxygen mixture, an MRI scan can detect the fine structures of soft tissue necessary to help doctors make more accurate diagnoses of many lung diseases. Scientists at Royal College London have discovered that xenon gas can help protect damaged nerve cells.

Xenon has been found to have an anesthetic effect for almost 60 years, xenon as an anesthetic does not react with various surgical materials, does not produce metabolites in the body, is now known to have the smallest impact on cardiovascular and cerebrovascular anesthesia, and unlike other anesthetics have toxic side effects on the human body. The application of xenon anesthesia has the advantages of fast induction, fast recovery, protective effect of the heart and nervous system, analgesic effect, small toxic side effects and other excellent characteristics, becoming an ideal anesthetic for high-risk patients such as pregnant women, heart patients and elderly patients. But at present, xenon production is far from enough to meet this potentially high demand. The main disadvantage of xenon anesthetics is their high cost, which can be reduced by xenon recovery devices.

The application of xenon in anesthesia continues to expand in the world, in Europe, xenon anesthesia is attracting people's attention, France liquid has a number of patents in this area, Europe's use of the field has reached 1 million demand.

The latest application of xenon in electronic chip manufacturing

The most recent use of xenon is in electronic chip manufacturing, and is the most important reason for the current increase in xenon demand and speculation in xenon. Several large chip manufacturers are using xenon plasma etching, mainly for the manufacture of microelectromechanical systems (MEMS). MEMS devices can integrate microelectronics and micromachinery into a whole, making more complex and powerful circuits on a single chip. The technology essentially combines a computer chip (which processes data) and a sensor (which collects it) into a single component that can be mass-produced. The potential uses for such chips are endless. Xenon etching is a process used by some semiconductor manufacturers to produce such superchips.

Application of xenon gas in flat panel TV manufacturing

The flat panel display market, especially plasma TVS, has played a large role in the increased demand for neon and xenon. Plasma display (PDP) is used to produce large-sized television displays (generally more than 32in), and the plasma display has thousands of small sealed low-pressure gas chambers arranged between two glass screens. The room is filled with a mixture of inert gases such as neon and xenon as a working medium.

Xenon applications in the space and satellite industries

Ion engines and ion plasma thrusters used for satellite launch use fuel xenon, because xenon weight and density is very heavy, the weight is about 4.5 times the weight of air, mainly used for satellite orbital position maintenance and maneuver control.

At the tail of the magnetic cavity of the ion engine, there is a pair of metal nets with positive and negative charges respectively, and the strong electromagnetic thrust generated by the positive charge and ammonia ions ejects the xenon ions at a high speed (about 100 OOOkm/h), and thus produces a recoil force to push the aircraft forward. Its thrust is much smaller than the chemical fuel engine, running at full speed, the ion engine per 2500W of electricity consumption can only produce l/llOkgf thrust, but it can run for months or even years, as a result, the vehicle eventually achieved the speed of the chemical fuel engine can reach 10 times.

The non-condensing nature of xenon allows ion rocket engines to start or shut down almost immediately, simplifying power distribution systems and insulator designs.

Xenon as a propellant has the following advantages: it is non-polluting and does not react chemically with spacecraft surface materials. Non-toxic, will not pollute the space environment and the Earth's biosphere. Ensure the health of the ground test personnel and the purification of the laboratory environment. The application of xenon ion rocket engines has expanded from the early days of stationary orbit satellite north-south position maintenance to attitude control, orbital maneuvering, non-propulsive applications as plasma switches and interplanetary navigation. Xenon particle engine, usually; A satellite's xenon particle engine consists of four xenon tanks (2:2 backup) and two power processors to maintain the satellite's orbital position. Each xenon particle engine consumes only 2.5 kg of fuel per year, so only 5 kg of fuel per year is needed to maintain satellite orbit. Xenon particles can produce more thrust, and because of its inert nature, it is not easy to corrode, but also safe. In the mid-1990s, this technology began to be used on a variety of satellites, typically using 60,000 L of xenon.
