It is commonly utilized as a catalyst in the petroleum industry, aiding in the refining process of crude oil. Lanthana is also employed in the production of optical glass, as it enhances the refractive index and optical properties of the material.

   Furthermore, lanthana finds its use in the manufacturing of electrodes for fuel cells and solid oxide fuel cells, where its electrical conductivity is advantageous. Another notable application of lanthana is in the synthesis of ceramic materials, as it improves the strength, durability, and thermal expansion properties of ceramics.

   Overall, lanthana is a crucial compound in several industries due to its unique properties and versatile applications. Its presence contributes to the enhancement of various materials, whether it be optical glass, ceramic materials, fuel cells, or catalysts for refining processes.

The word "lanthana" originates from Greek, where it was known as "lanthanein" (λανθάνειν). "Lanthanein" means "to escape notice" or "to be hidden" in Greek, reflecting the elusive nature of the element from which the word is derived. The term was originally used by the Swedish chemist Carl Gustav Mosander to describe a new rare earth element that he discovered in 1839. Eventually, this element became known as "lanthanum", and "lanthana" is derived from its name.
