Nano gold colloids with good stability

Our client said Nano colloidal gold and gold nanoparticles of Hongwu are unrivaled – we found that your company the best that we could work with.”

Colloid gold solution possesses unique properties such as good optical characteristics, biocompatibility, and catalytic activity. 

Made-in-china High purity metal W wolfram tungsten nanopowders with low price.

Molybdenum Nanopowders are available in 40nm, 70nm, 100nm, 130nm with the purity of 99.9% .

Nano Sno2 powder, 20nm, 30nm, 70-80nm with 99.99% purity, widely used in glass polishing agent. 

Our silver nanowires now could supply with diameter<30nm, length>20um,widely used as flexible display.

Multi-walled carbon nanotube dispersion is a carbon nanotube dispersion that is uniformly dispersed in an aqueous system by means of dispersion to form a liquid with good dispersibility and stability, which is not easy to stratify or precipitate, and is easy to add to application systems.

High purity carbon nanotubes are available for single walled, double walled, multi walled, with short tube 1-2um and long tube 5-20um. Adjustable purity, customized functionalized CNTs, dispersion, are available.

Nitrogen doped nano graphene,2% to 3% of graphene's carbon atoms replaced with nitrogen atoms to control electrical conductivity.

We have developed out more higher purity SWCNT, its purity could be reach to >95% or 99% , has excellent conductivity.

Silver nanowires are used for photoresist for its good properties. AgNWs show good flexibility, conductivity and used in capacitor touch screen and other devices.

Adding nano-silica to the hydrophobic anti-corrosion coating not only has good adhesion and corrosion resistance, but also has high density and permeability, and has a good waterproof effect.
