Abstract

Generally in glow discharge, either air or oxygen is used as the discharge medium and source of oxygen ions- It is dis-closed that carbon dioxide be used as the gas medium. The advantages are that under the same conditions of power, pres-sure, and time for air or oxygen; about 50 percent more oxide is grown when using carbon dioxide. In addition, the use of carbon dioxide avoids possible explosive conditions, e.g-, when oxygen is used as the source of ions.
