What is Nano Silver?
A nano-silver substance is a metallic silver substance that has a diameter below 100 nanometers. This usually ranges between 20 to 50 nanometers. These silver nanoparticles contain atoms made up of silver particles and not silverions. The solid silver nanoparticles are free of charge. The metallic-silver is made by chemical and physical methods into metallic silver particles with a diameter of less than 100nm. Silver nanoparticles, also known as black powders, are formed by mixing silver nanoparticles with media and substrates. The suspension of nanometers of silver in solution, or Nanometer Silver Solution, varies in color depending on the concentration. As the concentration increases, the color gradually darkens from yellow to deep-red. This liquid is composed of particles with a rough texture.
Because its size lies between an atomic cluster or macroscopic particle, the nano-silver dust has unique properties not found in ordinary silver powder.
1. Surface effect
Nano-silver powder refers to the effect on the surface of the particles that have been reduced in size and made into fine powder. It has a different surface than that of silver powder.
2. Volume effect
Volume effect in nano-silver powder refers to the decrease of volume and number of atoms within the particle. As the number and size of the nano silver particles decreases, so will the energy gap. Some electrical, magnetic, and thermal energies may be affected. You can intuitively see that the nano silver powder is darker than the silver-white particles with larger silver particles. It is due to significant changes in the non-absorption of emission, scattering and scattering caused by proton vibration characteristics and energy level discontinuity. This happens with smaller silver particles.
