low-pressure plasma

Low-pressure plasma is a state of matter created when gases are energized in a vacuum environment, causing the gas particles to become ionized—meaning they’ve lost or gained electrons. This ionization produces a mixture of ions, electrons, and neutral particles that together form plasma. Because the pressure is low, the particles are spread out, allowing for controlled reactions and precise surface treatments. Low-pressure plasma is used in various applications like cleaning, coating, sterilization, and material modification, providing an effective way to alter surfaces without high temperatures or harsh chemicals.
