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. 

Tin Copper SnCu Alloy Nanopowder could particle size at 70nm.

Nano sized Zinc oxide ZNO powders  antibacterial agent for the plastics industry.

Nano cobalt powder is magnetic, spherical, widely used in cemented carbides coating materials.

The general purity of Hongwu's MWCNT is 99%. If not high requirements, lower purity about 90%+ one is also available. For some application, low purity MWCNT would be more cost-effective.

Hongwu Nano supplies different carbon nanotubes, including single-walled, double-walled, multi-walled CNTs. Dispersion can be customized also. CNTs have excellent properties of catalyst, thermal, electric conduction, adsorption, mechanical, etc..

Silicon Dioxide with the size of 10-20nm, 20-30nm with the purity of 99.8% as the  electret material .

CAS 12249-45-5 Micron Silver coated copper particles with 5-35% Ag is a kind of high conductive material with good oxidation resistance and conductivity, low resistivity, high dispersion and high stability.
