Product Overview

 

The particle size of nano silver powder is usually between 1-100 nanometers. Compared with macroscopic silver particles, the particle size of nano silver powder is extremely small, which gives it unique physical and chemical properties. For example, when the particle size of silver particles decreases to the nanometer level, the proportion of surface atoms increases significantly, and the surface effect is significantly enhanced.

The particle size also affects the color of the nano silver powder. Generally speaking, as the particle size decreases, the color of nano silver powder gradually changes from silver white to yellow or even brown, due to the surface plasmon resonance effect of the nanoparticles. The absorption and scattering characteristics of silver nanoparticles with different particle sizes in the visible light region are different, resulting in different colors. Silver is an excellent conductive material, and due to its nanoscale effect, silver nanoparticles also have some special electrical properties while maintaining the good conductivity of silver. For example, the resistance of nano silver powder increases with the decrease of particle size, because the reduction of nanoparticle size leads to a decrease in the average free path of electrons, and the transmission of electrons in nano silver powder is subject to more scattering and obstruction.

Nano silver powder may exhibit quantum phenomena such as quantum tunneling at low temperatures. When the distance between silver nanoparticles is small enough, electrons can be transmitted between particles through quantum tunneling effect, which makes silver nanoparticles have potential application value in some nanoelectronic devices, such as preparing conductive connections and quantum dot contacts in nanocircuits. Nano silver powder has unique optical properties, mainly due to its surface plasmon resonance effect. When the frequency of incident light matches the oscillation frequency of free electrons on the surface of nano silver powder, strong absorption and scattering phenomena occur. This surface plasmon resonance effect endows nano silver powder with strong optical absorption and scattering capabilities in the visible and near-infrared light regions.

Product Features

Excellent conductivity: Nano silver powder has excellent conductivity and is an important material in the field of microelectronics.

Excellent antibacterial performance: Nano silver powder has strong inhibitory and killing effects on dozens of pathogenic microorganisms such as Escherichia coli, Neisseria gonorrhoeae, and Chlamydia trachomatis, and does not develop drug resistance. Its antibacterial performance is directly related to its particle size, and theoretically, the smaller the particle size, the stronger the bactericidal performance.

Excellent thermal conductivity: Nano silver powder also exhibits excellent thermal conductivity and can be used to prepare thermal interface materials to improve thermal conductivity efficiency.


Application Fields

 

High end silver paste: In the field of electronic technology, nano silver powder is widely used in the preparation of high-end silver paste, providing efficient conductive function for electronic devices

Conductive coating: Nano silver powder can be used to prepare conductive coatings, which theoretically can be applied in fields such as transparent conductive electrodes, anti-static coatings, electromagnetic shielding, etc.

Medical field: In the medical field, nano silver powder can theoretically be applied to medical devices, wound dressings, disinfectants and other products due to its excellent antibacterial properties, effectively inhibiting bacterial growth and reducing the risk of infection

Other fields: In addition, nano silver powder can also be used in various fields such as catalytic materials, new energy, electroplating industry, as well as green household appliances and home products

Our Dogs Are Obsessed. The Squeak Is Intense.
Style: Large Ball, Size: 3 Count, Style: Large Ball, Size: 3 Count
BLUF: Our dogs absolutely love these — the squeak is loud enough that we sometimes have to take them away. --- Our dogs went crazy for these the moment we opened the pack. They’re durable, super bouncy, and easily became the new favorite toys in the house. The only thing to know is that the squeak is loud — like “I need to take this away for a minute” loud. But honestly, that’s probably why the dogs love them so much. Great value for a 3‑pack and perfect for pups who enjoy a good squeaky toy.

A great toy for any dog!
Style: Small Ball, Size: 1 Count, Style: Small Ball, Size: 1 Count
The Hartz Duraplay ball is great! My 4 1/2 yr. old Pug has never liked playing with them before. He has gone crazy for this ball. He has no trouble grabbing it with is mouth. He ever gets it to squeak with his feet. I think it’s a great dog toy. Excellent!

Great Value and very durable
Style: Small Ball, Size: 1 Count
Very durable! We have purchased this for our new lab puppy. Highly recommend them. We have bought them before for our retrievers and it has been one of the longest lasting toys they own. Which says a lot because toys get torn up fast in our house. Definitely a good value and the material is easy on their teeth. Also it keeps ours busy for a while.

Aussie Approved
Size: Large, Color: Blue
I got a knock off one of these originally and man I should have just stuck with the real thing. My dog destroyed the other one in about 4 seconds. My dog loves this one and has not been able to tear it up, he prefers to just push it around after he gets all the treat out of it which is hilarious to watch. The quality is amazing and it is so easy to clean without leaving a smelly odor on it. It fits in my freezer perfectly and also is soft but firm so I do not have to worry about my dog hurting his teeth. For reference I have an Aussie and I got the large one which is perfect for his size (60lbs). My pet prefers this one over the last one for sure since this one actually keeps him entertained.

Awesome enrichment toy!
Size: Large, Color: Green, Size: Large, Color: Green
These are awesome! My dogs love them and keep them occupied for 30-60 mins so I can make and enjoy my coffee in peace before work. They are very easy to clean, but as others have mentioned, they can get stuck. I had to take a pliers to get one of them unscrewed. Hopefully that’s not a constant issue. I do wish they were more durable since there were a lot of teeth marks in them after the first use, so I upgraded to the black super chewer one. I’m happy I gave these a try and feel they are worth the money, especially for high energy dogs who get bored easily.
