产品介绍
金黄色有光泽金属,质柔软,富有延展性,1克金可拉成3000米金丝,可锤成只有0.00001毫米厚的半透明金箔。有良好的传热、导电性。主要氧化数+1、+3。化学性质很不活泼。在空气中不被氧化,不跟水、酸或强碱溶液反应。能溶于王水生成氯金酸HAuCl4。有氧存在时溶于氰化钾或氰化钠溶液。在空气中加热直到熔化都不发生氧化。金不溶于3种强酸,但溶于王水.氰化钾(钠)溶液。50°C与碘发生反应;60°C与氯、溴反应;100°C与氟反应。不与硫及硫化物反应。金与汞作用,可用混汞法提金。用作晶体管的部件、电接触合金、医药、装饰合金,大部用于货币和工艺品。在地球上分布广而稀少,多以游离态自然金形式存在,也有化合态的如碲金矿AuTe2。主要从岩脉金和冲积金矿提取。 超细金粉:主要主要用于电子工业厚膜浆料、多层陶瓷电容器内外电极材料。用于电子工业厚膜浆料、多层陶瓷电容器内外电极材料。
