Understanding Gas Plasma: The Fourth State of Matter
Gas plasma, often referred to as the fourth state of matter, is a fascinating and highly useful phenomenon. It’s created when a gas is energized to the point where its atoms are separated into electrons and positive ions. These charged particles, known as free radicals, give plasma unique properties that make it invaluable in numerous scientific and industrial processes.
How is Gas Plasma Generated?
For industrial and commercial applications, gas plasma is typically generated through the use of strong electric fields. These fields are most effectively produced by radio frequency equipment and microwave technology. At Crescend, we specialize in solid-state microwave generators that offer superior control and efficiency in plasma generation.
