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. 

Hongwu brand Flake nickel powders（Diameter: 5-20um,Thickness: 0.1-1um，Purity: 99%+） have potential applications in coatings, catalysis, magnetic storage materials, electromagnetic shielding and electromagnetic absorption.

Boron Carbide Nanopowder (B4C) supply in 500nm with high quality , for further information please contact us.

Factory price Black Nano Copper Oxide Powder/nano Cuo for catalyst with high quality is the hot sell procuct in China.

Nano Ni-Cu alloy powder, high purity, uniform particle size, good sphericity, dispersion, and sintering shrinkage is small, dark black powder.

In high crystallinity matrix resin, adding materials with high thermal conductivity is the most effective method to improve plastic thermal conductivity.The thermal conductive filler is refined and even nano size is made, which not only has little effect on mechanical properties, but also improves thermal conductivity. With the addition of nanometer magnesium oxide Magnesia Nanoparticles of high purity, good whiteness, small particle size and uniform particle size, the thermal conductivity is made up of ordinary 33W/(m).K) raised above 36W/(m. K). It can be used in PA, PBT, PET, ABS, PP, organic silicone, coating and other materials to play the role of thermal conduction. Thermal conductive agent: this product has excellent thermal conductivity, suitable for thermal interface materials, such as thermal plastic, thermal resin castable, thermal silicone, thermal powder coating, functional thermal conductive paint and various functional polymer products. The thermal conductivity can reach 3.4w/m.k. when 80% high-purity nanometer magnesium oxide is added into PPS. When 70% aluminum trioxide is added, the thermal conductivity can reach 2.392W/m.K. Notice: Nano Materials have lots of applications that we canot list one by one. And the applications we listed is theorically available according to characteristics of certain Nano Material and researches. For practical applications we would strongly advise you to have sample for testing. Thanks.
