Note: according to user requirements of nano particle can provide different size products.

Product performance

Application of Au nanopowder:

1.gold nano particleis used for a radiation-control coating for spacecraft.

2. For electronic tubes, as gold-plated grid wire, to give high conductivity and suppressing secondary emissions.

3. Gold nano powder and gold sheet is used for soldering semiconductors, with gold having a good ability to wet silicon at 371°C (725°F)

4. Gold powder also is used as a plating material, where sodium gold cyanide is used as a gold plating solution. The plating has good chemical resistance and electrical properties, however the plating lacks wear resistance, in which case gold-indium plate is utilised.

5. Gold alloys also have a number of applications such as:

1) Gold-gallium and gold-antimony are used in electronic industry (primarily as wire)

2) Nano gold powder is used for dental applications and is rightly termed dental gold, where gold is alloyed with silver, platinum and on occasion palladium. It is sometimes alloyed with iridium for hardening.

Storageof Au nanopowder:

Au nanopowder should be sealed and stored in a dry, cool environment, away from direct sunlight.
