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 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. One suspension of nanometersilver is nanometer solution. It has a color that changes with increasing concentration. As the concentration rises, the color gradually becomes deeper, from yellowish 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
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. As the nano silver particles have fewer atoms, there will be an increase in energy gaps in their energy bands. Some electrical, magnetic, and thermal energies may become abnormal. 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.
