Frequently Asked Questions About Plasma Technology
These frequently asked questions clarify key aspects of plasma technology and its potential.
What exactly is plasma technology?
Plasma technology harnesses the power of plasma, which is often referred to as the fourth state of matter. In essence, it’s an ionized gas containing ions and free electrons. Applying this energized gas allows us to alter material surfaces, synthesize new materials, or even sterilize equipment.
How is plasma technology different from using regular gas?
The key difference lies in the energy level. Regular gas molecules are in a stable, neutral state. Plasma, on the other hand, is an energized state where atoms have lost electrons, creating highly reactive ions and electrons. This increased reactivity allows for unique material interactions.
