Molybdenum is added to the rare earth oxide , molybdenum greatly improved performance . In recent years , increasing attention molybdenum application industry 's attention. Molybdenum is mainly used in high-precision electronic warfare and narrowband satellite communications , tubes , electric light and other fields. In the electronics industry , vacuum electronic devices are a large vacuum and gas -based electron (ion ) produce a variety of effects , amplified , converted signal is active devices,  tungsten balls  , launch tubes , microwave tubes, camera tubes , display tubes, vacuum optoelectronic devices, vacuum switch tube , X-ray tubes, new lighting , and gas lasers. Molybdenum narrow strip , foil , light industry mainly for sealing quartz glass , electric vacuum tubes, traveling wave tubes ,  tungsten electrode  lamps , high pressure mercury lamp , high pressure sodium , metal halide lamps , television lamp . Vacuum , gas-tight sealing of pipe materials have been using pure molybdenum foil , molybdenum rod . In such a tight molybdenum foil tube , vacuum production process, when the temperature reaches the softening temperature of the quartz glass 1800 ℃ , the pure molybdenum foil recrystallization , the plastic drop rapidly showed severe recrystallization brittleness clip tight seal during the molybdenum disc rupture great possibility. Rare molybdenum at 1800 ℃ when its plasticity and creep properties are good, molybdenum disc rupture phenomenon does not occur .
