Uses

Uses & Benefits
  • Tin and bismuth alloys have a very low melting point and hence it is used in fire detector and the fire extinguishers. It also used in electric solders and fuses.
  
  • It is used for producing chip resistors and contact.
  • Ruthenium oxide is used to coat the anodes cells for chlorine production in chemical industry. It also works as catalysts for ammonia and acetic acid reaction.
