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 aluminum-silicon alloy powder, 70nm, Al:Si=88:12, could supply other particle size.

For Silicon nanoparticles battery use and dispersion, we are professional and can supply high quality powders.

High quality Carbon Nanohorn nano powders available in Outer diameter:2-5nm,Length:10-20nm.

Nano platinum powders have excellent catalytic properties and are widely used with good performance. Hongwu Nano have produced and supplied Pt nano materials with good and stable quality, competitive prices for years. Adjustable particle sizes, customized water dispersion are available.

Footballene C60 is widely used in diamond thin film growth and super lubricant.

Carbon nanohorn is a new allotrope of carbon found in recent years. It can be seen as a single layer of graphite, one end is an angular closed structure and the other end is an open structure.

Graphite powder could be available in 40-50nm, 80-100nm and micron size 1um, 99.95% purity,widely used in batteries.

Single-walled Carbon Nanotubes aqueous dispersion is a customized material for easier usage in water base. The concentration of SWCNT water solution can be adjusted. Besides SWCNT type, double and multi walled CNTs dispersions are also available.
