Electronic and electrical materials

Electronic appliances are the industry with the largest amount of silver, and its use is divided into electrical contact materials, composite materials and welding materials. Silver and silver-based electrical contact materials can be divided into: pure silver, silver alloy, silver-oxide, sintered alloy. The annual output of silver and silver-based electrical contact materials in the world is about 2900~3000 tons. Composite materials are materials prepared by composite technology, which are divided into silver alloy composite materials and silver matrix composite materials. From the perspective of silver saving technology, silver composite material is a kind of new material with great development prospect. Silver welding materials such as sterling silver welding

Silver - copper solder, etc.

Photosensitive material

Silver halide photosensitive materials are one of the most used fields of silver. The largest production and sales of several types of photographic materials are photographic film, photographic paper, X-ray film, fluorescence information documentary, electron microscope photographic film and printing film. In the 1990s, the amount of silver used in the world photography industry was about 6,000 to 6,500 tons. Due to the development of electronic imaging and digital imaging technology, the amount of silver halide photosensitive materials has been reduced, but the application of silver halide photosensitive materials is still irreplaceable in some aspects, and there is still a large market space.

Chemical materials

Silver has two main applications in this regard, one is used as a catalyst, such as widely used in REDOX reactions and polymerization reactions, for the treatment of sulfur-containing industrial waste gases, and the other is electronic electroplating industrial preparations, such as silver pulp, silver potassium gasification, etc.
