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. 

In the machining industry, sub-micron ultra-fine copper powder is very easy to combine with iron, aluminum and other metal materials alloyed materials, as a wear-resistant repair material.

With ultrasonic time and surfactant concentration increases, the powder dispersion after first increases and then decreases.

Copper oxide nanopowders has good catalytic performance, widely used in desulfurizer.

Superfine Boron Nanoparticles is available for 100-200nm with 99%. Amorphous B Powders can be used in various fields. Mircon size 1-2um B powder is also supplied. Quick delivery, competitive price of amorphous Boron particles are offered by Hongwu Nano.

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

Micron size, flake morphology, Bright Silver Powder, 99.99% high purity, with different particle size for customers' choice.  It is widely applied for conductive paste.

Ferroferric Oxide have 100-200nm with 99% purity use as the magetism and the catalyst in the filed.

High hardness, wear-resisting zirconia ceramic dolly is the best choice in the milling of electron, printing ink, paint, coating which require high and no pollution.

Single Layer Graphene Powders as the most lightest and thinnest material in the world which will replace an ideal material for the manufacture of silicon transistors in the hyperfine field of microelectronics in the future.
