The corona discharge, its properties and specific uses

Abstract

The main properties of corona discharges are reviewed, with emphasis on the features which make them unique for use as non-equilibrium chemical reactors : Their stability and ease of operation over a wide range of gases and pressures, including atmospheric; their sharply confined ionization regions where hot electrons interact with cold gas, inducing reactions without back reactions; and their extended low field drift regions which act as gaseous electrolytes, inducing electrochemical reactions on surfaces.Present and future applications are discussed : Synthesis of ozone and ammonia, promotion of flames and combustion, surface treatment, and electrical insulation improvement. © 1985 IUPAC
