THE USE OF RHENIUM AND ITS ALLOYS IN ELECTRONIC VACUUM DEVICES,
Abstract
The article reviews the applications of rhenium and its alloys in cathode electronics and their use as structural parts of electronic devices, etc. The properties of rhenium as a thermionic emitter are discussed and compared to those of tungsten, tantalum, and molybdenum. The emissive properties of rhenium-barium cathodes are described. The uses of rhenium as base material for high-temperature cathodes are treated at length; the thermionic emission characteristics of rhenium-, tantalum-, niobium-, and molybdenum-base cathodes coated with thorium oxide, yttrium oxide, lanthanum oxide, and europium oxide are compared. Rhenium is also discussed as a field emitter, and as a material for heating elements when it is alloyed with tungsten.
