Charateristics:

1. Gold powder is soft, ductile and the most ductile metal, so it is usually alloyed to improve strength and durability. Gold has a low reflectivity for ultraviolet and visible light, but a high reflectivity for infrared and red wavelengths.
2. Gold powder is a good thermal and electrical conductor, not affected by air, nitric acid, hydrochloric acid or sulfuric acid and most other reagents. A mixture of nitric acid and three portions of hydrochloric acid (called aqua regia) can dissolve gold. It is also dissolved by the azoimide solution. In addition, it is also attacked by sodium, potassium cyanide and oxygen.


Application of nanometer gold powder:

1. Gold powder used for radiation control coating of spacecraft
2. For electron tubes, such as gold-plated grid wires, it has high conductivity and suppresses secondary emission.
3. Gold powder and gold flakes are used for soldering semiconductors. Gold has a good ability to wet silicon at 371°C (725°F)
4. Gold powder can also be used as an electroplating material, where sodium cyanide gold is used as a gold plating solution. The coating has good chemical resistance and electrical properties, but the coating lacks abrasion resistance, in this case a gold-indium plate is used.
5. Gold alloys also have many applications, such as:
1) Gold gallium and gold antimony are used in the electronics industry (mainly used as wires)
2) Gold powder is used in dental applications and is correctly called dental gold, where gold is alloyed with silver, platinum and palladium. Sometimes alloyed with iridium to harden.


nanometer gold powder should be stored in dry, cool and sealing of the environment, please don't be exposure to air, besides should avoid the heavy pressure, according to ordinary goods transportation.
