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. 

Barium titanate is a perovskite-type ferroelectric, with excellent ferroelectric, dielectric, pyroelectric and optoelectronic properties.

      Titanium dioxide material can selectively etch metal nanoparticles through electron transfer with metal Ag nanoparticles in the excited state, and change the optical absorption characteristics of the material, thus the Ag/Tio2 nanomaterials can change color under the light excitation of different wavelengths.       Experimental demonstration: 1) 500 ℃ heat treatment was carried out on the TIO2 thin film，it is helpful for photocatalytic deposition of Ag particles, and Ag/TIO2 thin film has the obvious photochromic phenomenon; 2) as the content increase of Ag particles deposited on TIO2 films, the photochromic rate of Ag/TIO2 films increases correspondingly, but the reaction rate of photochromic reaction is inhibited when the content of Ag particles exceeds a certain amount.       If you're interested in the material, please not hesitate to contact us , and we will make a tailor for matching your products.

α-phase nano-alumina powder is spherical, high purity 99.99%, widely used in ceramic materials.

Graphene nanoplatelets has good thermal conductive,widely used in plastics.

Y2O3 yttrium oxide nanopowder is widely used as high temperature infrared ceramic material

CAS 12249-45-5 Micron Silver coated copper particles with 5-35% Ag is a kind of high conductive material with good oxidation resistance and conductivity, low resistivity, high dispersion and high stability.

cutting tools used 99.9% Titanium Diboride nano powders (tib2) available in 100-200nm.

Hongwu supply flake silver powder with particle size 1-15um, high purity 99.99%, and they're widely used in touch screen low temperature silver paste with excellent condution performance. Differenet apparent density and SSA are available.

The general purity of Hongwu's MWCNT is 99%. If not high requirements, lower purity about 90%+ one is also available. For some application, low purity MWCNT would be more cost-effective.

60-80nm Zirconium Oxide Nanopowders with the purity of 99.9% as the fireproof material.
