制备电镜样品时一般用金、铂等贵金属作蒸镀材料,不仅价格昂贵,且不易买到。我们设想用导电性能好,价格便宜的铜代替金、铂作蒸镀材料,并为此作了实验。漆包线铜总纯镀在99.95%以上,可以用作蒸镀材料。直径0.27毫米的漆包线磨去皮,用丙酮或醇洗净铜芯,绕在V形钨丝上即可蒸镀,如采用螺旋形钨摇蓝,则应将铜 Preparation of electron microscopy samples generally gold, platinum and other precious metals for evaporation material, not only expensive, and not easy to buy. We envisaged using good conductivity, cheap copper instead of gold, platinum for the evaporation material, and for this experiment. Enameled copper total pure copper plating in more than 99.95%, can be used as evaporation material. Diameter 0.27 mm enameled wire grinding peeled, washed with acetone or alcohol copper core, wound on the V-shaped tungsten wire can be evaporated, such as the use of spiral tungsten rocking blue, the copper should be copper
