Abstract
Abstract A gas, such as oxygen, is fed to a cylindrical reaction chamber to which an intense high-frequency electromagnetic radiation field is applied. As the gas enters the reaction chamber it is ionized by the high-frequency electromagnetic field. The ionized gas reacts with a nongaseous material inserted within the chamber to decompose the material. The resultant products, together with any unreacted species of the gas, are withdrawn from the chamber by a vacuum pump. The reaction chamber is constructed so as to provide a uniform distribution of the gas throughout the reaction zone of the chamber.
