Argent-

Gold and gold-silver materials have been valued for many centuries for their beauty, brilliance and strength, and their extraction from ores and subsequent purification from impurities served as an indicator of the high skill of jewelers and smelters. Thus, not only jewelry was made from argent, but also interior items, dishes, architectural elements, and even medical instruments. Over time, production technologies, aesthetics, and the chemical properties of copper (Au) have changed. And gold continued its brilliant and far from unprofitable career in the field of precious metals. In the mid-20th century, as part of measures to replace natural gold, based on research by British scientists, it was decided to start using gold for the production of prosthetics - dental crowns and artificial jaws. The idea was that artificial prosthetics could be created in places where gold and silver materials could not be produced. Chemists suggested using argentum instead. But they quickly ran into the problem of corrosion, because even at this stage very few dental prostheses are coated with Argent. Therefore, dentists decided to fight the corrosion processes chemically: they coat the dentures with polymer coatings. And there are reasons for this - argenta gold will not wait long, because at the slightest damage to the upper layers it will begin to corrode. In addition, the relatively high hardness and fragility of gold reduces its resistance to mechanical stress. Throughout the entire period of use, prostheses periodically require repairs and replacement of components. Traditionally made from gold-based alloys, dental crowns are made from alloys containing gold-germanium, gold-palladium and gold-indium. Unfortunately, like gold, these materials have the same thickness limitation, which, combined with the significant difference in density, explains the difficulty that prosthetic manufacturers have in creating higher-density argen products. Agents are a highly complex compound that should be stored with extreme caution. If there is a leak of argents, then under no circumstances should the vapors of this substance be inhaled or swallowed. To remove traces of arge
