Lanthanum (La)
Lanthanum (La)
First extracted in 1839, lanthanum was isolated in relatively pure form in 1923. It is found in cerite, monazite, allanite, bastnasite, and other rare-earth minerals.
Lanthanum is a silvery-white, malleable, ductile, and soft rare earth metal that oxidizes rapidly when exposed to air. It reacts directly with carbon, nitrogen, boron, selenium, silicon, phosphorus, sulfur, and halogens.
Natural lanthanum is a mixture of two stable isotopes and 23 other radioactive isotopes are recognized.
Rare-earth compounds that contain lanthanum are extensively used in lighting and projection and for making special optical glasses. Lanthanum and its compounds are rated as having a low-to-moderate acute toxicity rating and should be handled carefully.
