Lanthanum: uses

The following uses for lanthanum are gathered from a number of sources as well as from anecdotal comments. I would be delighted to receive corrections as well as additional referenced uses.

  • rare-earth compounds containing lanthanum are extensively used in carbon lighting applications, especially by the motion picture industry for studio lighting and projection
  • 203La improves the alkali resistance of glass, and is used in making special optical glasses
  • small amounts as an additive are used to produce nodular cast iron
  • hydrogen sponge alloys containing lanthanum reversibly take up to 400 times their own volume of hydrogen gas. Heat is released, therefore these alloys have potential in energy conservation systems
  • lighter flints
  • alloys
