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.

Silver-coated copper powder is made of advanced electroless plating technology. After specific molding and surface treatment processes, different thicknesses of silver plating are formed on the surface of ultra-fine copper powder. 

High filling & low viscosity flake silver powders for epoxy resin conductive adhesive use       Conductive adhesive is a special kind of adhesion agent, mainly composed of resin and conductive fillers, such as silver powder, gold powder, copper powder, nickel powder, graphite powders, etc.), can be used as adhesive materials in microelectronics components, encapsulation manufacturing process.         Conductive adhesive with flake silver powder has excellent electrical conductivity, adhesion and chemical stability. Silver powder almost not be oxidized in the rubber, in air its oxidation speed is very slow, even if is oxidized, silver oxide generated still has good electrical conductivity. therefore, in the market, especially on the high reliability requirements of electric installation, flake silver powders as conductive filler is used mostly. And in the choice of matrix resin, epoxy resin is the best because of its high content of active group, high cohesive strength, good adhesion and excellent mechanical properties.       HW NANO flake silver powder, with particle size <1um, 1-3um,5-8um,10um, purity 99.99%. Specific surface area and apparent/bulk density are adjustable flexibly. It is available with small quantity for researchers and bulk order for industry groups.          Silver powder filling quantity influence on the properties of conductive silver glue. after silver powders as conductive filler is added to the epoxy adhesive, the conductive mechanism is the contact between of silver powders.After system curing, silver powders connect into chain circuit with each other, presents the conductivity. the data shows that the adding quantity of silver powder to 80% or so, the conductivity is the best.  

Rhodium Rh Nanopowders have 20-30nm with 99.95% purity use as the electric instrument and  chemical industry.

Silicon carbide has the characteristics of corrosion resistance, high temperature resistance, high strength, good thermal conductivity, and impact resistance. At the same time, it has the advantages of high thermal conductivity, oxidation resistance, and good thermal stability. It is often used in packaging materials in the microelectronics industry.

Hongwu Nano produces and supplies stabke and high quality Multi Walled Carbon Nanotubes(MWCNTs) with adjustable diameter from 10-100nm and short and long length, as well as functionalized CNTs, customized dispersion as per requirements.

Nano-zinc oxide is a high-end fine inorganic product that exhibits many special properties such as non-migratory, fluorescence, piezoelectricity and UV scatter. Using its wonderful properties in light, electricity, magnetism, and sensitivity, it can manufacture gas sensors, phosphors, varistors, UV shielding materials, image recording materials, piezoelectric materials, varistors, high-efficiency catalysts, magnetic materials, and plastic films. . It has been proved by practice that nano zinc oxide is widely used in various fields such as rubber with its excellent properties.

Nanometer cuprous oxide has potential applications in solar cells, sensors, superconductors, hydrogen production and electrochromism. Some experts even predict that nanoscale cuprous oxide can be used in the environment to deal with organic pollutants.

With β-Sic do electronic packaging materials, heaters, heat exchangers have high thermal shock resistance, good thermal conductivity,

Our Antimony Tin Oxide nanopowders(ATO <10nm) is widely used in transparent antistatic coatings basis on highly dispersion.
