Colloidal Gold Nano Gold Solution:
Colloidal gold benefits:
Nanogold is made by using high purity gold as raw material, through a special new processing technology to make gold particle size of 15nm or less, greatly improve the inherent characteristics of gold, such as catalytic effect, free radical removal effect, dispersion effect and so on.
Gold symbol is Au. The properties of gold include high security, high stability, oxidation resistance, corrosion resistance, etc.
Gold is one of the rarest and most precious metals. It has a face-centered cube structure and an atomic weight of 196.96654.
Physical property of gold:
Gold melting point: 1064.43. Gold boiling point: 2808. electronegativity: 2.54, covalent radius: 1.34A, ion radius: 0.85 (+3) A, atomic radius: 1.46A, atomic volume: 10.2cc/mol.
Gold can form alloys with many metals because the atomic radii of these metals are very close to the atomic radii of gold; The atomic radius of gold is 1.46 angstroms;1.46 Mr. Bi;1.44 Mr. Silver; Platinum 1.39 Mr.Thus gold can be formed in alloys of gold and silver, gold and copper, gold and platinum, etc. These alloys are not compounds, but solid melts.

Gold nanoparticles colour :
Gold nanoparticles or au nanoparticles can look red, orange, or even blue. The color depends on the size and shape of the nanoparticles and the distance between them.
Product Performance of Colloidal Gold Nano Gold Solution CAS 7440-57-5:
Colloidal gold is prepared by dispersing 15nm or even smaller gold nanoparticles into the water solution. The preparation will end up with a uniform neutral solution with stable color. The nano gold solution appears to be faint red, not golden brown. The gold liquid appears to be azury when in the condensed state by adding other substances. The solution is edible for human beings and totally safe for skin contact.
