Product Code : PO-Ag-2N-CU
Silver is a soft, malleable metal with a characteristic sheen. It has the highest thermal and electrical conductivities of all metals. It is generally found uncombined, or in the sulfide or arsenide ores from which it can be recovered as a cyanide complex which is subsequently reduced to the metal, in aqueous solution, by the use of zinc. The pure metal is stable to water and oxygen but is attacked in air by sulfur bearing compounds to form the characteristic black layer of silver sulfide. It is soluble in sulfuric and nitric acids. Some silver salts are sensitive to light (e.g. AgI, AgCl and AgBr) and are of fundamental importance to photography.
ATT is a professional supplier of high-purity Silver powder. The purity can be 99.99%(4N), 99.995%(4N5), 99.999%(5N). Our standard powder particle sizes average in the range of - 325 mesh, - 100 mesh, 10-50 microns and submicron (< 1 micron). We can also provide many materials in the nanoscale range. We also produce Silver as rod, ingot, pieces, pellets, disc, granules, wire, and in compound forms, such as oxide. Other shapes are available by request.

Product Information
Silver is a soft, malleable metal with a characteristic sheen. It has the highest thermal and electrical conductivities of all metals. It is generally found uncombined, or in the sulfide or arsenide ores from which it can be recovered as a cyanide complex which is subsequently reduced to the metal, in aqueous solution, by the use of zinc.

Some silver salts are sensitive to light (e.g. AgI, AgCl and AgBr) and are of fundamental importance to photography. Other applications and industries in which silver is used include the manufacture of jewellery (both as the pure metal and as a constituent of various alloys), the electrical industry (e.g. in the manufacture of contacts) and for the silvering of glass. Sterling silver contains 92.5% silver. The rest is copper or some other metal. It is used for jewelry and silver tableware, where appearance is important. Silver is used to making mirrors, as it is the best reflector of visible light known, although it does tarnish with time. It is also used in dental alloys, solder and brazing alloys, electrical contacts, and batteries. Silver paints are used for making printed circuits.

Applications of Silver Powder
Silver Powder (Ag) can be applied in the following fields: Jewelry, silverware, electronic equipment, electrical contacts, dental alloy fillings, photographic processing, batteries, solder/brazing alloys, and disinfecting water. Some silver salts are sensitive to light (e.g. AgI, AgCl and AgBr) and are of fundamental importance to photography. Other applications and industries in which silver is used include the manufacture of jewellery (both as the pure metal and as a constituent of various alloys), the electrical industry (e.g. in the manufacture of contacts) and for the silvering of glass. Sterling silver contains 92.5% silver. The rest is copper or some other metal. It is used for jewelry and silver tableware, where appearance is important.
