What is plasma?
Plasma is the fourth state of matter, the others being solid, liquid, and gas. Plasma typically consists of a mixture of ionized species, electrons and neutral particles. The sun is made up of plasma with inside temperature reaching 10,000,000 degrees Celcius. In nature, we can observe plasma in lightning strikes and with the Northern Lights (Aurora Borealis). Examples of man-made plasma include the light produced by a neon tube, as well as plasma cutting systems used to slice through metal. Thermal plasma can readily reach temperatures in excess of 10,000 degrees Celcius. At PyroGenesis, we harness the unique properties of thermal plasma to melt and transform metal, to carry out high temperature chemical reactions and to convert waste into energy.
