Silver in Jewelry and accessories
The main use of this metal, in addition to coins, has been in general use throughout the history ‎of jewelry making and other items, and this issue continues. Examples include silverware, ‎which is very suitable due to its antibacterial properties. Because pure Silver is very soft, it ‎alloys more with copper.‎

Silver in medicine
In medicine, this Metal is embedded in wound dressings and is used as an antibiotic coating in ‎medical devices. Wound dressings containing sulfadiazine or silver nanomaterials are used to ‎treat external infections. Silver ion is bioactive and in sufficient concentration easily kills ‎bacteria in vitro.‎

These ions interfere with the enzymes that produce nutrients and the formation of cell walls, ‎and also bind to the genetic material of bacteria. Silver nanoparticles are used as antimicrobials ‎in a variety of industrial, hygienic, and domestic applications.‎

Silver in electronics
This metal is very important in electronics for conductors and electrodes because of its high ‎electrical conductivity even when stained. Silver and compressed silver foils are used to make ‎vacuum tubes and are still used today in the construction of semiconductor devices, circuits, ‎and their components. Silver powder and its alloys are used in the preparation of pastes for ‎conductive layers and electrodes, ceramic capacitors, and other ceramic components.‎

Silver in solder alloys
Silver solder is used for Metals such as cobalt, nickel, and copper, and steel-based alloys. The ‎main components of these solder alloys are silver and copper, and other elements are selected ‎according to the specific application, which includes zinc, tin, cadmium, palladium, ‎manganese, and phosphorus. This metal increases efficiency and corrosion resistance during ‎use.‎

Silver in Chemical equipment
This metal is useful due to its low reactivity, high thermal conductivity, and easy efficiency in ‎the manufacture of chemical equipment. This equipment for working at high temperatures is ‎often silver plated. Silver and its alloys with Gold are used as seals, wires, or rings for Oxygen ‎compressors and vacuum equipment.‎

Silver as a catalyst
This metal is a suitable catalyst for the oxidation reaction. Powdered silver leads to the ‎complete oxidation of organic matter to carbon dioxide and water, and hence coarse-grained ‎silver is used instead. Dehydrogenation of methanol to formaldehyde at 600-720 ° C is ‎performed using silver gas or its crystals as a catalyst.‎

Caution with using silver metal
Silver compounds are less toxic than other heavy metals because they are poorly absorbed ‎during digestion and what is absorbed is rapidly converted to insoluble silver compounds or ‎complexed by metallothionein.‎

However, silver fluoride and nitrate are caustic soda and can cause tissue damage as well as ‎gastroenteritis, diarrhea, hypotension, muscle cramps, paralysis, and respiratory arrest. ‎Animals that frequently consume silver salts experience anemia, growth retardation, necrosis ‎of the liver and kidneys.‎

In high doses, the metal and its compounds can be absorbed into the circulatory system and ‎stored in various tissues of the body, resulting in a blue-gray pigment in the skin, eyes, and ‎mucous membranes.‎

Some silver compounds, such as Nitrogen azide, amide, acetyl, oxalate, and silver (II) oxide ‎compounds, are highly explosive; they can explode on heating, impact, light, and sometimes ‎spontaneously. To prevent the formation of such compounds, Ammonia and acetylene should be ‎kept away from silver equipment.‎
