Precious(Noble) Metals And Their Applications
Precious metals are distinctive metals that are very scarce in nature. And generally, precious metals are chemically inactive. These precious(noble) metal group consist Silver(Ag), Gold(Au) and Platinum(Pt). Because of their scarcity, their applications are also very less. These applications are generally where the amount of requirements of these noble precious metals are less. But these noble metals has also very unique properties.
What Are The Properties Of Noble Metals?
- Silver(Ag): Silver has very attractive appereance that shiny silverish color. Because of this property, Silver is used as coinage and precious jewelry throughout history and today. Also Silver(Ag) has very specific properties. One of these specific properties of Silver is the highest electrical conductivity around metals. Because of this property, Silver can be used in electronical circuits. Also silver is used as filling in dental applications.
- Gold(Au): Gold is the one of the most precious metals. Because of this precious of Gold, it is used in jewelry and coinage throughout history. Gold has very specific shiny yellow color appearance. Because of this color, Goldis very attractive metal. Gold has also very specific features such as very good electrical conductivity and high corrosion resistance. Because of this, Gold is used in electronical applications. Also Gold is used in dental work, and plating onto other metals for decorative purposes.
- Platinum(Pt): Platinum is the most precious metal around all metals. Becuase of this expensive nature of Platinum, it is used in jewelry. But applications of Platinum include loys of kinds of areas. These areas include kinds of applications as thermocouples, electrical contacts, spark plugs, corrosion resistant devices, and catalytic pollution control equipment for automobiles.
As you see above, precious metals has also very specific properties. Even their expensiveness, they can find very important application areas in engineering.
