Silver was one of the metals found in ancient times.
It silver although there is 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 silver color is white, mixed with impurities metal luster, soft quality, hardened after impurities, color gray and red. The melting point is 961.93 ° C, the boiling point is 2212 ° C, and the density is 10.5 grams/cubic centimeter (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.
