Extension information:
. Silver is a metal single quality, the element symbol is AG, which is rich in ductility. It is very good thermal conductivity and conductive performance. Metal.
silver, that is, silver, because of its white color, it is called silver, and it is opposite to gold. Use it to make currency and decorations. It was called silver when doing currency in ancient times. Pure silver color is white, mixed with impurities metal luster, soft quality, hardened after impurities, color gray and red. The proportion of pure silver is 10.5, the melting point is 960.5 ° C, and the conductive performance is good, which is dissolved in nitric acid and sulfuric acid. Silver was one of the metals found in ancient times. Although silver also has a single quality in nature, most of them exist in the form of a combination. Silver has a high ductility, so it can be crushed into a transparent foil with a thickness of only 0.3 microns, and 1 gram of silver particles can be pulled into about two kilometers long filament. Silver thermal conductivity and conductivity are among the best in metal.
. The importance of silver
Pure silver color is white, with metal luster and soft. The melting point is 961.93 ° C, the boiling point is 2212 ° C, and the density is 10.5g/cm3 (20 ° C). Silver is soft, with good flexibility and ductility. The ductility is second only to gold. Soluble in nitric acid and sulfuric acid. The reflection of silver to light reaches 91%. At normal temperature, halogen can slowly combine with silver to generate silver. Silver does not react with dilute hydrochloric acid, dilute sulfuric acid, and alkali, but can produce chemical reactions with strong oxidized acid concentrated nitric acid and concentrated hydrochloric acid.
The main use of silver is mainly based on three pillars: industry, photography and jewelry silverware. The total demand for silver in these three categories accounts for about 85%of the demand for silver.
Since ancient times, silver has been with gold as a symbol of wealth. The chemical symbol of the silver is AG, from Latin Argertum, which means "light, bright". Because the color of the silver is white, it is called "silver".
SBM not only has good electrical conduction characteristics, but also has high photosensitive and luminous characteristics. It is applied to industry, photography, jewelry, currency manufacturing and other aspects.
Compared with gold, silver is sufficient and low in terms of silver, so it is used in the field of circulation more and enters the circulation field. Many countries have established silver -based systems and use silver coins as mainstream currencies.
. The history of silver
In ancient times, humans had awareness of silver. Silver, like gold, is a precious metal with a long history, which has a history of more than 4,000 years. Due to the excellent characteristics of silver, people have given it dual value of currency and decoration. The silver dollars used by the British pound and my country's pre -liberation are silver and copper alloys based on silver. In the Qing Dynasty in my country, 1 two silvers were about 400-500 yuan (Changmei Note) today.
is more lively than gold than gold. Although its abundance in the crust is about 15 times the gold, it rarely exists in a single texture, so its discovery is late than gold. In ancient times, people already knew the mining silver mine. Because the amount of silver obtained at that time was small, it made it more valuable than gold. From 1780 to 1580 BC, the Code of the Egyptian dynasty stipulated that the value of silver was twice the value of gold, and even in the 17th century, the value of Japan and silver was equal. The earliest silver was used for decorations and tableware, and later used as a currency.
silver, that is, silver, because of its white color, it is called silver, and it is opposite to gold. Use it to make currency and decorations. It was called silver when doing currency in ancient times. Silver, always shining with the moonlings of the moon, the original meaning of silver thesis, which means "bright". my country also often use silver characters to describe white and shiny things, such as Galaxy, Ginkgo, Silver Fish, Tremella, Screen, etc.
Stin and bronze in ancient my country was often tied with gold and copper, which was called "only gold three grades". The book "Yugong" records "only gold". It can be seen that my country was found silver as early as the 23th century BC, that is, more than 4,000 years ago. In nature, silver often exists in the form of sterling silver, and people have found a piece of silver weighing 13.5 tons! In addition, there are also existence in the form of chloride and sulfide, and they are often coexisting together with lead, copper, coriander, arsenic and other ore.
. The nature of silver
physical properties
The abundance, which is a metal with good thermal conductivity and electrical conductivity. The first electricity off energy is 7.576EV. The chemical properties are stable and do not work for oxygen in water and atmosphere; easily dissolved in dilute nitric acid, hot concentrated sulfuric acid, hydrochloric acid, and melting sodium hydroxide.
The crystal structure: The crystal cells are noodle cubic cells, and each crystal cell contains 4 metal atoms.
Chemical
The characteristics of the silver are 1, and their chemical properties are worse than copper. At room temperature, or even oxygen in water and air, it can change in the air. Black, losing silver white luster, this is because H_S in the silver and air synthesizes the black AG_S. Its chemical response equation is:
silver cannot release hydrogen with dilute hydrochloric acid or dilute sulfuric acid, but silver can be dissolved in nitric acid or hot concentrated sulfuric acid:
Under the condition of heating, halides can be generated:
It silver has a strong synthesis of sulfur. When heating, it can directly synthesize AG_S:
. Industrial application
electronic appliances
is the industry with the largest amount of silver. It is divided into electrical contact materials, composite materials and welding materials. Silver and silver-based contact materials can be divided into: pure AG, silver alloy, silver-oxide, and burning alloy. The annual output of silver and silver -based contact materials around the world is about 2900 to 3000T. Composite materials are made of composite technology, which are divided into silver alloy composite materials and silver -based composite materials. From the perspective of silver technology, silver composite materials are a new material with great development. Silver welded materials such as sterling silver welds, silver -copper solder, etc.
Mensensitive material
The silver light sensitivity material is one of the areas with the largest silver amount. At present, several of the most producing and sales volumes are photography film, photo paper, X-light film, fluorescent information documentary, electronic microscopy photos and printing films. In the 1990s, the amount of silver used in the world was about 6000 to 6500T. Due to the development of electronic imaging and digital imaging technology, the amount of silver lighting materials has been reduced, but the application of halogen silver lighting materials is still irreplaceable in some aspects, and there is still a lot of market space.
Mochemical and chemical
silver has two main applications in this regard. One is silver catalysts, such as widely used for oxidation reduction and polymerization reactions, and used industrial exhaust gas containing sulfide. The second is electronic electroplating industrial preparations, such as silver pulp and potassium cyanide.
The craft jewelry
silver has seductive white luster, higher chemical stability and collection value value, which is favored by people (especially women). Therefore Make jewelry, decoration, silverware, tableware, congratulations, medals and commemorative coins. Silver jewelry has a broad market in developing countries, and silver food has a popular family. The silver commemorative coin is exquisitely designed, the circulation is small, and has the function of preserving and value -added. It is favored by coin collectors and coin investors. In the 1990s, the use of cointests only maintained from 1,000 to 1500T each year, accounting for about 5%of the consumption of silver.
