摘　　要：制备了微细金粉,通过粉末冶金法将金粉与钨粉试制成两相单体均匀混合的粉末,得到一种耐磨性能较高,耐蚀的AuW(16)电触点材料。利用金与钨的化学性质的差异,将金从金钨合金中分离提纯出来,回收贵金属金,回收率为99.93%。A AuW（16）electric contact material with high performance of wear and corrosion was produced by powder metallurgy using mixed powders of tungsten powder and fine gold powder.Gold was recovered according to the differences in chemical properties of gold and tungsten from AuW（16）electric contact material.
