                                         high purity gold nanopowders/ Au powders


Specification:

20-30nm, 99.99%, spherical

 

Properties:

1.Gold powders is soft, ductile and the most malleable of metals, and because of this is usually alloyed to give improved strength and durability. Gold’s reflectivity of ultraviolet and visual light rays is low, however it has high reflectivity of infrared and red wavelengths.

 

2.Gold powders is a good conductor of heat and electricity, and is unaffected by air, nitric, hydrochloric, or sulphuric acid and most other reagents. A mixture of one part nitric acid with three parts hydrochloric acid, called aqua regia, dissolves gold. It is also dissolved by solutions of azoimide. Further, it is attacked by sodium, and potassium cyanide plus oxygen.


Application:


1.Gold powder is 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 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)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.

 

 For the further information of the gold powder please contact us freely.
