Nano gold particle is good for catalyst for its excellent properties. Fine gold powder with 20-30nm, high purity 99.99%. Besides Au nanoparticle, colloidal gold can be also customized. Professional manufacturer of precious metal nano materials.

Nano gold particle for catalyst, fine gold powder 20nm, Au nanoparticle

Specification of gold nano particle:

MF: Au

Particle size: 20-30nm,adjustable from 20nm-1um

Purity: 99.99%

Properties:

1. Gold nano particle is a soft, ductile and the most malleable of metal, and it 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. Nano gold particle is a good conductor of heat and electricity, and is unaffected by air, nitric, hydrochloric, or sulphuric acid and most other reagents.

Application of the gold nano particle:

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.
