We manufacture high-performance "precious metal chemical products" used in antibacterial agents and conductive pastes!

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)

basic information

■Silver Chloride AgCl - White amorphous powder or coarse lumps - Almost insoluble in water or acids - Soluble in ammonia water, alkaline cyanide solution, and sodium thiosulfate solution It is used as a reference electrode for silver/silver chloride electrodes in electrochemical measurements. Micronized silver chloride powder can be mixed with a binder to create a paste. Using silver chloride paste, biosensors can be produced through printing methods. It has recently gained attention as it allows for direct printing of sensors onto clothing. Standard packaging: 500g (poly bottle), 1kg (poly bottle) ■Silver Acetate CH3COOAg - White needle-like or plate-like crystalline powder - Soluble in nitric acid - Difficult to dissolve in water It is actively developed for research and development of new materials such as integrated circuits (IC), fine ceramics, and functional ceramics. It is also used in nicotine replacement chewing gum. It meets a wide range of diverse needs in various fields, including organic synthesis and environmental measurement reagents. Standard packaging: 500g (poly bottle), 1kg (poly bottle) 【Applications of Silver Compounds】 ■Conductive paste ■Electronics component plating ■Plating ■Catalysts ■Reagents ■Antimicrobials, etc.
