Since ancient times, people known white shiny metal.Silver (Ag) has been widely used as a material for ornaments.Its properties have been applied in full disinfecting effect masters for the production of household utensils.
Pure Silver - very soft and flexible material.The shape of the crystal lattice structure of silver has the form of a cube with edges to center.From a gram of the metal can be two-kilometer stretch a thin wire.The high density (10.5 g / cm3) allows the silver by weight compete with lead.But on such qualities as electrical and thermal conductivity, silver is not from competitors.Silver spoon in a glass of boiling water heated with incredible speed, and the use of silver components (conductors, contacts, terminals) in the construction of various radio shows their high quality and extraordinary technical characteristics.
melting point of silver in the 962 ° C makes it easier to handle it.Silver alloy with different metals are widely used in various fields.A small admixture of copper in its composition makes the metal harder and more acceptable for the manufacture of a variety of products.
melting point of silver is of importance not only during use, but also production.Furthermore, for the metal together with vyplavlivaniem ore from a number of chemical methods of extraction such as cyanidation and amalgamation.
practically not oxidized in air, silver is capable of dissolving large volumes of gas.Even in the solid state it is heated to 450 ° C, it has the ability to absorb the amount of oxygen in excess of five times its size.For silver, in the liquid state, this figure rises to 20 volumes.Knowing the temperature at which silver is easy to reproduce in the laboratory the beautiful but dangerous experience.Cooling body suddenly starts to behave unusually.Produce oxygen breaks the crust solidifying on the silver surface with great force, producing an effect of spontaneous splashing.
Initially it had value as a metal material for jewelry.Attractive appearance, ease of handling, extraordinary flexibility and a low melting point of silver along with its healing properties of the products created this image of metal ornaments for health.Modern jewelers but the combination of silver with precious stones, learned to do on the surface of gold tipped.The technology of this process takes into account the temperature at which melt gold (1064 ° C) and at a silver (962 ° C).Using a combination rarely found, the master jeweler's managed to achieve high quality products at a lower cost them.
The use of this metal in the art based on other, equally attractive properties than a ductility and a relatively small melting point of silver.At the dawn of electronics engineering silver actively used in various radio details.As a rule, the quality and reliability of these devices there are special requirements.Recently, there was a significant displacement of silver through the use of new materials.
Ddlya silver found work in film and photography.First Ike - transmitting tube in television - also not without the use of silver.
widely used in modern home appliances Silver is not as a great conductor of electricity, and as a substance with a unique decontamination action.Various filters, parts for medical equipment, washing machines and refrigerators are made using silver compounds.With this technological solution works ions agents in carrying out its antiseptic activity.
silver due to its unique properties, is widely used in various sectors of human activity.Beginning his story with decorations, it is composed of complex technical devices had been in space.It has become a party to scientific and technical progress, find use in a wide variety of radio products.I make the audience laugh and cry and the first cinema viewers.Finally, it has been used in household appliances as a powerful tool for cleaning and disinfection.
