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 Nano produces iridium nanopowder and iridiium dioxide nanopowder in size of 20nm-1um with 99.99%purity.

Antimony Doped Tin Oxide have excellent heat insulation powder, conductive powder

20nm Nano Silver Particles Antibacterial Principle for more inductry application.

Cobalt nanopowder, 100-150nm, 99.9%,widely used as magnetic materials, or absorbing materials.

Hongwu International Group Ltd supply customized service for high stable rhodium nanoparticle dispersion as per requirement.

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.  

Diamond nanoparticles is superhard, superfine, high spec surface area, could be used to make nano diamond polishing liquid. 

Flake silver conductive powders has 1-2um or 3-8um particle size, widely used in low temperature conductor paste.

Rutile Type Nano Titanium Oxide, shielding ultraviolet ability and excellent transparency, has excellent compatibility with other raw material.

Because nano ceria/cerium dioxide(CeO2) has good catalytic properties, it is widely used in electrolyte materials; it is also used in ozonated water treatment, with excellent performance, good stability and catalytic effect.
