Abstract
Abstract An improved ozone generator includes a cryogenically cooled reaction chamber in which gaseous oxygen well below the boiling point of ozone is subjected to a corona discharge and forms liquid ozone. The discharge portion of the reaction chamber holds a body of liquid ozone to block the flow of unreacted oxygen from the reaction chamber. A bed of glass particles within the body of liquid helps to suppress explosive decomposition of the ozone. A temperature gradient across the discharge portion of the reaction chamber permits the ozone to volatilize to a gas and exit the reaction chamber in a smooth, controllable manner.
