3 Uses
3.1 Uses & Benefits
  • It has no commercial uses, but its alloys are in high demand. Lanthanum and Nickel alloy is used for the hydrogen gas storage.
  • The best-known use for mischmetal alloy of Lanthanum is; as a ‘flints’ for cigarette lighters.
  • Terbium salts are used in optical devices like laser devices.
  • Terbium’s alloy lengthens and shortens the magnetic field and this effect forms loudspeaker.
