Conductive Composites
Silver nanoparticles conduct electricity and they are easily dispersible in any number of other materials. Adding silver nanoparticles to materials such as pastes, epoxies, inks, plastics, and various other composites enhance their electrical and thermal conductivity.
1. High-end silver paste (glue) :
Paste (glue) for internal and external electrodes of chip components;
Paste (glue) for thick film integrated circuit;
Paste (glue) for solar cell electrode;
Conductive silver paste for LED chip.
2. Conductive Coating
Filter with high-grade coating;
Porcelain tube capacitor with silver coating
Low temperature sintering conductive paste;
Dielectric paste
Future development direction of solar cell market:
Mainly using diamond line black silicon technology and PERC technology.
Hongwu's sub-micron silver powder---through the control of particle size, the slurry in the sintering process can be quickly filled into the black silicon gap, so that it is easier to form a good contact.
At the same time, due to the reduction of particle size, the melting temperature of silver powder in the sintering process also decreases, which is consistent with the PERC technology requirements of greatly reducing the sintering temperature process.
Silver nanoparticles have excellent catalytic activity and can be used as catalysts for many reactions. Ag/ZnO composite nanoparticles were prepared by photoreduction deposition of precious metals. The photocatalytic oxidation of gas phase n-heptane was used as a model reaction to study the effects of the photocatalytic activity of samples and the amount of noble metal deposition on the catalytic activity. The results show that deposition of Ag in ZnO nanoparticles can greatly improve the photocatalyst activity.
The reduction of p - nitrobenzoic acid with silver nanoparticles as catalyst. The results show that the reduction degree of p-nitrobenzoic acid with nano-silver as catalyst is much greater than that without nano-silver. And, with the increase of the amount of nano-silver, the faster the reaction, the more complete the reaction. Ethylene oxidation catalyst, supported silver catalyst for fuel cell.
