摘　　要：利用液-固混合法制备的含稀土氧化物的钨基合金材料,经加工制成小功率金卤灯电极,并组装成70W的金卤灯整灯。对不同电极材质的金卤灯测定发光特性,并进行分析对比,钨镝和钨镝钇合金电极的金卤灯的启动、防溅性能和抗腐蚀性能可达到钨钍合金电极的水平。Electrodes produced by tungsten alloy which doped with rare earth by liquid-solid doping technique are used in low power metal halide lamps, and manufactured of 70 watts metal halide lamps.By measuring radiate characteristics of metal halide lamp, which is produced with various kinds of earth oxides as electrodes and analysis.It is shown that the properties of electrode's start-up,sputter-proofing and corrosive-proofing doped with dysprosium and yttrium oxides are match with ThO2-W electrodes.
