The element 'lanthanum' was named in 1839 when a Swede named 'Mossander' discovered other elements in the town soil. He borrowed the Greek word 'hidden' to name this element 'lanthanum'.
Lanthanum is widely used, such as piezoelectric materials, electrothermal materials, thermoelectric materials, magnetoresistive materials, light-emitting materials, hydrogen storage materials, optical glass, laser materials, various alloy materials, etc. It is also applied in catalysts for preparing many organic chemical products, and lanthanum is also used in light conversion agricultural films. In foreign countries, scientists have dubbed the effect of lanthanum on crops "super calcium".
