Chapter X inorganic insulation

The past year's literature on insulation indicates increased activity in the fields of glass and thin-film dielectrics accompanied by slightly less work on mica and vitrified silicates. Several specific areas deserve mention. A greater effort was made to distinguish between cationic, anionic, and electronic mechanisms of charge transport in glass and crystalline oxides, particularly the defect cubic structures. More thin films were made by decomposition processes than before, and increased attention was given to negative resistance phenomena and the fundamental limitations in achieving good dielectric properties in insulating films. A host of glasses was examined in the USSR for glass electrode properties.
