What is silver used for? 9 most common uses
The Use of silver There are hundreds, mostly in industrial, commercial, and even personal processes. Its corrosion resistance makes it ideal for the manufacture of special containers or for coating other metals.
Silver is an off-white metal. It is a chemical element that appears with the number 11 in the periodic table and that has an atomic number of 47. It comes from the Latin "argentum" which means white or light.
It is one of the seven metals that have been counted since ancient times and are mentioned in the Book of Genesis. On the islands of the Aegean Sea, they indicate that silver was separated from lead four millennia ago before our era.
Among its most prominent features is that it is white, shiny, soft, malleable, and stretchy. It is very common to find it in nature. Silver is a by-product of the processing of copper, zinc, lead and gold.
From a chemical point of view it is a very heavy metal and from a commercial point of view it is a very valuable precious metal.
The first people to come into contact with silver attributed divine properties to it.
It is estimated that 70% of silver production is used in industrial activities and the other 30% in monetary activities, a good part is also used in goldsmithing.
However, its main uses are in the photographic, chemical, medical and electronic industries.
What is the use of silver and what are its most common uses?
It is used very often in electronics because of its high conductivity. Silver can be found again and again in integrated circuits and computer keyboards.
Silver is also used to make electronic components and high-speed semiconductor cables with excellent conductivity. Diesel locomotives have pure silver contacts that help generate electricity.
Silver is necessary for the development of photographs because of its sensitivity to light, especially because it contains bromide and iodide.
Although it is a toxic material, it is used for topical application. An example is silver nitrate, which is poured on the skin to get rid of warts.
One of its most common and oldest uses is estimated in coins (from around 700 a.C.).
First alloys of gold and silver were used, then pure silver. There are still countries that use silver to mint coins, although most use nickel because of the great value silver has acquired over the past 200 years.
In this one of the most famous uses of silver is framed. Every year jewelry is made as rings, necklaces, bracelets, anklets, earrings and silver piercings.
Traditional jewelry has silver as one of its most important materials for making all types of jewelry.
In many industrial tasks it is necessary to alloy silver with other metals to make them harder and more conductive.
It is common to find silver alloys with lead or thallium to coat parts of the aerospace industry or to reinforce dental parts.
It is also usually alloyed for welding and making electrical contacts. An elementary material for electric batteries is precisely the silver alloy with zinc.
It is good to avoid oxidation reactions. One example is the production of formaldehyde from methanol and oxygen.
8 - arithmetic
In the manufacture of computers, composites formed primarily from silver are used to connect the microprocessor board to the base of the dissipator. This cools the processor.
9 - White weapons
Also known as melee weapons, knives, swords, spears and arrowheads are still made, which are mainly made of silver.
Silver is also used to make mirrors with great light reflection. These mirrors are not very common because the ones people usually have in their homes are made of aluminum and sand. Traditionally, mirrors were made with silver inlays.
In medicine, some antiseptics are made from silver. Such is the case of the dilute solution of silver nitrate (AgNO 3) which is used as an antiseptic and bactericide; The type of silver used to make this solution is known as colloidal silver.
Previously, when there was back projection of films with tape, silver was used to reveal the light from the film.
And that is that the silver halides are light sensitive and are essential to be able to shoot the film with the right colors and shadows.
In times of drought, silver, along with other chemical components, was used to bombard and rain the clouds.
However, this option has been curtailed as experts say that performing this action is harmful to planet Earth, as the introduction of these chemical agents deforms the normal functioning of nature.
Generally, silver is found in low concentrations in the environment. Indiscriminate use of silver in the environment involves a number of physical and chemical changes as the soluble compound of it can react to a variety of substances such as chemical and organic elements of water.
When we talk about people, silver can be just as deadly depending on the given use. We used to say that it would be accepted as silver nitrate for topical application i.e. the skin. But when we talk about silver in the organism, it can really be fatal.
The compounds of the soluble salts that come from the silver in a concentration of 2 g can be fatal if they are ingested.
Concomitant damage ranges from skin pigmentation and wear and tear to the cornea of the eye and death from poisoning.
The mere fact of exposure to its fumes causes dizziness, suffocation, lightheadedness, vomiting, diarrhea, and even a coma.
