  • 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
