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. 

Nano copper oxide, 30-50nm, 99.5% purity, black powder. widely used in metal electrode materials.

MWCNTs Multi Walled Carbon Nanotubes Aqueous Dispersion can be produced with different diameter (10-100nm), lengths(short 1-2um, long 5-20um) and adjusted concentration 2%-5%.

Copper is the basis of functional powder material of high-tech and high value-added, but also one of the fastest developing areas of materials hot products.

We could do nano silver wires at smaller diameter <60nm, with high electrical conductivity.

Silver nanoparticles samples in stock and larger quantity in bulk wth more competitive price.

Competitive price for COOH multi-walled carbon nanotubes with all kinds of diameter and length, 99% purity. Besides COOH, OH, NH2, nickel coated, nitrogen doped types are available.

High purity nickel nanoparticles, superfine, magnetic materials,used for efficient catalyst.

China factory direct offer ultrafine 10nm Pd nanopowders, average particle size, high purity 99.95%, goods catalyst performance. Good and stable quality for both testing orders and batch orders. COA, SEM, MSDS available. Any need welcome to contact us! 

Titanium dioxide nanopowder has good thermal stability, hydrophilic, widely used in white pigment.

Zinc Oxide Nanopowders with the white color as the famous white pigment  use to the printing and dyeing, paper making.
