Silver nano powder market is expect a fast growth

Nowadays natural resources are far not enough to meet applications need, especially when it comes to high-tech and high-end products and rise new market needs.
Today we’ll discuss the market growth of a high-tech raw material silver nano powder.

1.Silver nano powder is widely used in the electronic industry: High-end silver paste (glue) chip components for external electrode pulp; thick film integrated circuit pulp; solar cell electrode paste, LED chip package with conductive silver plastic; used in printed electronic devices such as conductive ink, etc. The growth of electronic industry will help the growth of silver nano powder.

2.Silver nano powder is widely used for antibacterial. Since silver nano powder’s lasting and special antibacterial function, it is applied to produce antibacterial products: antibacterial Medicine and medical equipment; antibacterial plastic, rubber products, textiles and clothing footwear; antibacterial coatings, ceramics and glass; green antibacterial coatings green home appliances and furniture products etc. More and more manufacturers use silver nano powder to meet market antibacterial need and trend, also take it as a selling point, which customers will buy.

3.Silver nano powder as catalytic, materials Ethylene oxidation reaction catalyst, fuel cell with a supported silver catalyst New energy heat exchange material, etc. Since the small size and high specific surface area, silver nano powder is widely used as catalyst.

In the past years, many researchers are made to explore and testing special applications of silver nano powders in different areas. And now many of them has proved to work good and detailed application technology has get matured. Together with the industries it applied for grows fast. To conclude, silver nano powder are expected a fast growth.

Ultrafine Silver Powder Used for Conductive Silver Pastes

Ultrafine Silver Powder Used for Conductive Silver Pastes

Advantages: flexibility, conductivity, good printability, different rheological performance
The composition of the Silver conductive slurry requires different types of silver powders (such as the commonly used silver powders, of which particle size between 0.1 microns and 10 microns) or combined as conductive filler, and even different formulations in each category require different silver powders as conductive function materials.
Object: To achieve maximum utilization of silver conductivity and thermal conductivity with the least amount of silver powders in the established formulation or film forming process, to optimize the performance and cost of film properties.

General classification of Ultrafine Silver Powders in Electronic industry:

1. High – temperature sintered silver conductive paste with high sintering active silver powders
2. High – temperature sintered silver conductive paste with high dispersion silver powders
3. High conductivity reduction silver powders
4. Bright silver powders
5. Flake silver powders
6. Coarse silver powders

Application of Conductive Silver Pastes

1.The application in the electronics industry

For a variety of touch screen, film shape, electronic toys, computer keyboard, remote control and other electronic products, to play a part in conductive, thermal, shielding and so on.

2.Application in Solar Energy Industry

Solar conductive paste is one of the most important materials of solar energy, solar cells in addition to the most important material other than silicon, and solar energy conversion efficiency is closely related. (The solar cell back electrode and the front electrode are used silver paste)

Solar cell requirements for the slurry:
Forming a good ohmic contact, low contact resistance
Good wire conductivity
Strong adhesion strength
High aspect ratio
Wide sintering process window
Good chemical stability
There are suitable for large-scale production process
Low price
Solderability, solderability

Because of good performance of ultrafine silver powders used in conductive silver pastes, it’s a good choice in solar energy conductive pastes.

Silver nanopowder for antibacterial

Antibacterial mechanism of nano silver powder

Nano-silver particles can enter inside the micro-organisms, interrupt RNA replication to stop it’s reproduction , meanwhile it attached to the microbial cell wall, the impact of microbial organisms transmission finally cause the cell’s rupture and death.

Advantage of nano silver powder in antibacterial application

1) Disinfection and sterilization effect is good, lasting and have no drug resistance problem.

2) small amount at ppm level nano-silver antimicrobial products means lower cost.

3) without shortcoming of allergies and excessive deposition as traditional silver salt antibacterial agent do.

4) non-toxic to human safety, environmentally friendly.

Speak of nano silver powder, it’s like a far away high-technology topic, but speaking of specific, detailed antibacterial applications, we know nano silver particle can be part of our daily life.

Food

No doubt people consume food every day, and silver nano particle could take pat in our daily life in the way of antibacterial food container. Since nano silver have an inhibitory effect on the common food contamination bacteria (Gram-positive bacteria, Gram-negative bacteria, yeast, mold, etc.), it is applied to produce antibacterial food containers: nano silver food crisper, nano silver plastic wrap, antibacterial ceramic tableware, antibacterial refrigerator

Clothing

Nano silver’s antibacterial works as well as on fabrics, try search nano silver antibacterial socks on your online purchasing platforms, there surly comes out lot of results. In fact, some researchers does experiments and proves that nano silver particle function more than merely antibacterial part, also fabrics’’ anti-static and far infrared performance is also improved by nano silver finishing.

Living

Nano silver is also widely used in building materials: Nano silver antibacterial coatings, nano-silver antibacterial paint, etc., they are coated on the surface of the plate can kill the surface attached bacteria, and the antibacterial effect is lasting.

Medicine

No doubt that antibacterial work is more critical when it comes to the matter of health. And yes nowadays nano silver particle is maturely applied into medicines. For example: nano silver antibacterial dressings, nano silver antibacterial gel, nano silver antibacterial catheter, nano silver antibacterial equipment, nano silver bone cement, etc. I cannot list them all.
