What is arc cold plasma?

Arc cold plasma is a type of plasma that is generated at atmospheric pressure. It is produced by passing a high voltage electrical discharge through a gas, typically helium or argon. This produces a plasma that is relatively cool compared to other types of plasma, with temperatures ranging from a few thousand to tens of thousands of degrees Celsius.

Arc cold plasma has numerous applications in various fields such as material processing, surface treatments, medical treatments, and environmental applications. It is used for surface modification and cleaning of various materials, including metals, plastics, textiles, and ceramics. It is also used for sterilization and decontamination of medical equipment, surgical instruments, and biological tissues. Additionally, arc cold plasma is utilized for wastewater treatment and air purification by removing pollutants and microorganisms.

The unique properties of arc cold plasma, including its relatively low temperature and the ability to operate at atmospheric pressure, make it a promising technology for a wide range of applications. Its use is expected to grow in the future as more research is carried out to explore its potential.
