Nano-Silver Powder (Ag) Description
Nano-silver powder (Ag)
, also known as silver nanoparticles or colloidal silver, is a particulate form of silver that comprises extremely small particles typically below 100 nanometres. Due to its high surface area to volume ratio, these particles exhibit defined properties that render them effective in various applications.
Nano-Silver Powder
is recognised for its antimicrobial and antibacterial properties. The silver nanoparticles are able to release silver ions, which inhibit the growth of bacteria, fungi and other micro-organisms. This property makes the powder valuable in the medical, textile and water treatment industries, where it is employed in products such as wound dressings, antibacterial coatings and disinfectants.
Furthermore, nano-silver powder finds application in the electronics, catalysis and conductive inks sectors due to its excellent electrical and thermal conductivity. It is used in the manufacture of circuit boards, solar cells, conductive adhesives and sensors.
