Application
- batteries
- Batteries made of silver compounds have high energy density and massive energy absorption capacity and are capable of generating heavy current at low inner resistance.
- coins
- This precious metal is highly valued as it is used for making commemorative coins.
- awards
- Medals with high silver content remain stable when exposed to atmosphere.
- microwave ovens
- Due to its high conductivity and oxidation resistance, silver is used for coating the inner surface of wave guides.
