COMPARATIVE-STUDIES OF THERMAL EMITTERS MADE OF MOLYBDENUM MONOCRYSTAL

New materials for thermal emitters based on cheap and available molybd enum which combine high ionization efficiency and convenient service o f iridium, rhenium and platinum have been developed. Thermal emitters from molybdenum molybdenum monocrystal alloyed with iridium, rhenium, platinum and tungsten allow higher operating temperatures (<900 K) whi ch permits them to be applied in analyzing high-temperature and high-m olecular amines and their derivatives. New efficient thermal emitters for surface ionization detectors show better stability and reliability in long-term service at elevated temperature (<900 K).
