金黄色有光泽金属,质柔软,富有延展性,有良好的传热、导电性。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。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。
Golden shiny metal, soft in texture, rich in ductility, with good heat transfer and conductivity. The chemical properties are very inactive. It is not oxidized in the air and does not react with water, acid, or strong alkaline solutions. Used as components for transistors, electrical contact alloys, pharmaceuticals, decorative alloys, mostly for currency and handicrafts. It is widely distributed and rare on Earth, mostly existing in the form of free natural gold, as well as in the form of chemical compounds such as tellurium gold AuTe2. Mainly extracted from vein gold and alluvial gold deposits. Ultra fine gold powder: mainly used for thick film paste in the electronic industry and as electrode material for multi-layer ceramic capacitors. Used for thick film paste in the electronic industry and as electrode material for multi-layer ceramic capacitors.
