he doped tungsten wires of resistance to high-temperature creep-sag have been successfully produced. By means of liquid-liquid mixing easily water-soluable AMT with K. Al. Si and spraying and drying. The properties of the doping powders, bars and wires of new process are different from those of common doping method. The average value of remanent elongation is less than 1.0mm for several high-temperature creep-sag tests.The proportion of first-grade wires is about 100%.
