Nano Silver Powder (Ag) Description
Nano silver powder (Ag), also referred to as silver nanoparticles or colloidal silver, is a form of silver composed of particles that typically measure less than 100 nanometres. The particles, owing to a high surface-area-to-volume ratio, exhibit specific properties that allow their use in various applications.
Nano silver powder is recognised for its antibacterial and antimicrobial properties. The silver nanoparticles are capable of releasing silver ions, which inhibit the growth of bacteria, fungi and other microorganisms. Consequently, the powder is used within the medical, textile and water treatment industries, where it is incorporated into wound dressings, antibacterial coatings and disinfectants.
Furthermore, nano silver powder is employed owing to its reliable electrical and thermal conductivity in electronics, catalysis and as a conductor in conductive inks and pastes. It is also utilised in the manufacture of printed circuit boards, solar cells, conductive adhesives and sensors.
