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 International Group Ltd supply both 20nm-1um iridium/Ir and iridium dioxide nanopowders with 99.99% purity.

Our beta micron silicon carbide whisker widely used in wear-resisting ceramic materials.

Photocatalytic Materials Superfine Anatase Titanium Dioxide TiO2 Nanopowders.

Nano Antimony Tin Oxide Particle/ATO Nanopowder can be sued as Catalyst Carrier/Support for it has good electrical conductivity, chemical stability and good mechanical attrition properties similar to metals and it helps improving catalytic performance for precious metals.

Precious metal Ruthenium nano powder is available for 20-30nm with 99.95% purity. It can be used as hardener for its good properties. Besides 20-30nm Ru particle, size can be adjustable from 20nm-3um. Its oxides RuO2 nanopowder also available. Nano Ru Dispersion can be customized.

nano Pt ( platinum ) particles water dispersion, concentration 1000ppm ( 0.1%) nano Pt is widely used as catalyst, making into dispersion make it easy and convenient for customer use.

Factory wholesale good dispersed silver nanowire powder and solutions, the detailed spec as follows: 1. D 20-40nm  L 10-30um. 2. D 30-50nm  L 10-30um. 3. D 50-70nm  L 10-30um. 4. D 70-110nm L 20-60um. 5. Customized size.       We provide our customers:   Customized high quality silver nanowire in forms of powder, solution or dispersions   Batch production technolgoy and Volume competitive pricing   Reliable service   Technical assistance       Silver nanowires are silver gray, can be stored as a colloidal suspension in different solvents, such as water, ethanol, isopropanol, etc. Diameter ranges from 10 nanometers to hundreds of nanometers, and can be controlled.       Silver nanowires, due to its small size, large specific surface, has a good chemical properties, catalytic performance, antibacterial performance and excellent biocompatibility. Currently in optics, electronics, catalysis, information storage, medicine and energy silver nanowires have important applications. unlike silver particles, as in three-dimensional direction are in nanometer scale, the size effect, quantum effect and surface effect more apparent, and Silver particles can be widely used in conductive paste additives and catalyst. Silver nanowire, in addition to having traditional  electrical conductivity, ductility and tensile properties of silver particles,  have different electrical, optical features, can be added in a variety of products as additives for modifying material.  

1.Hardness close to natural diamond, lighter than the metal, never wear, never change the color and so on.

Graphene nano sheet,is high conductivity and good flexibility, used to reinforced expoxy resin.
