The powder of gold has a dark yellow color, has a high density.
Belong to refractory compounds with a high degree of plasticity, corrosion resistance, ability to pressing.
It is a good conductor of heat and electrical current.
For hardening, gold is cold-formed under pressure. On the surface of the powder does not form films. It has high strength and wear resistance.
Chemical composition of Gold powder
|Base element||Impurities, not more than (%)||Density (g/cm3)|
|Powder particles less than:||% share in total mass|
Powder of gold is used as a material for laboratory research, in the production of jewelry, as a material for sputtering gold coatings.
Gold powder mixed with gallium powder is used as a solder for soldering metals by diffusion.
