What is Nano Silver?
A nano-silver substance is a metallic silver substance that has a diameter below 100 nanometers. This usually ranges from 20-50 nanometers. These silver nanoparticles contain atoms made up of silver particles and not silver ions. The solid silver nanoparticles are free of charge. Metallic silver can be made by chemical and physical methods from the metallic-silver. 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 many unique properties not found in ordinary silver powder.
1. Surface effect
The nano-silver powder refers to the effect on the surface of the ultrafine particles that have been reduced in size and made more surface atoms. 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 the number atoms within the particle. As the number and size of 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.
