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. 

Fullerenes were discovered many organic reagents have high chemical activity, which have machine chemical reaction to introduce polymer chemistry can be used for synthesis of fullerenes and design derived polymers.

Permanent Magnetic Alloy Fe-Cr-Co Powder.

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.

HW offer silver powder with flake morphology, micron size or sub-micron size, works good for conductive use

Black graphene oxide as the catalytic materials apply to the chemical industry.

rhodium nanopowder, 20-30nm, 99.99%, widely used in hydrogenation reactions.

Nano Tin Dioxide material is widely used in the field of lithium batteries due to its good permeability to visible light, excellent chemical stability, and specific conductivity and infrared radiation reflection characteristics.

Good Conductive and good heat conduction Graphene Nanoplatelets

Silicon nanopowders sepcification: 30-50nm 99%+, brown yellow, good spherical 100-200nm 99.9%+,brown black, irregular crystal form 300-500nm 99.9%+,brown black, irregular crystal form 1-2um 99.9+%, dark brown, irregular crystal form Silicon nanopowder properties: High purity, good dispersion performance, small size, uniform distribution, large surface area, high surface activity, low apparent density. Nano Silicon powders is non-toxic, odorless, and with active features. Nano silicon powder is a new material for high capacity lithium battery anodes. Silicon nanopowders use for the rechargeable lithium battery cathode material: Due to the high absorption rate of nanometer silicon and lithium batteries, the nano silicon for lithium can significantly increase the capacity of lithium battery (theory can reach 4000mA / h). Nano silicon powder and graphite replace the nano carbon powder as raw materials for the lithium anode material, use the mechanical milling method for preparing the best ratio of silicon / graphite composites, silicon and graphite, which is 1:9. Composition Si-C composite material, can effectively reduce the expansion when silicon absorption lithium ions, increase the affinity with the electrolytic solution, and easily dispersed and can improve the cycle performance. Nano silicon nanowires made of silicon powder used in rechargeable lithium battery anode material in or on the surface of the nano silicon powder coated graphite anode materials used in rechargeable lithium battery, rechargeable lithium batteries can be improved more than three times the capacity and charge-discharge cycles.
