Silver has unique characteristics, including excellent antibacterial effects and photosensitivity. Its antibacterial properties have been known since ancient times, and it is said to be one of the oldest medicines used in ancient Egypt. Even today, many products are being developed that utilize silver's antibacterial power. A well-known product that takes advantage of its photosensitivity is the photosensitive agent used in film photography, which employs silver halide made from silver nitrate. ■ Silver Nitrate AgNO3 - Shiny crystals or white crystalline powder - Extremely soluble in water - Slightly soluble in ethyl alcohol It is used as a starting material for synthesizing various silver compounds! Silver has the highest electrical conductivity, thermal conductivity, and visible light reflectivity among metals at room temperature. It is used as silver powder for conductive paste to take advantage of its electrical conductivity and as a raw material for silver plating solutions. Efforts are also actively being made to develop silver powder as a die adhesive for LEDs and power semiconductors to utilize its excellent thermal conductivity. Additionally, silver's outstanding reflectivity is utilized in the reflective surfaces of mirrors. Standard packaging: 500g (poly bottle), 1kg (poly bottle), 10kg (poly bag)
