Lanthanum metal is a white-silvery material at standard pressure and temperature. Lanthanum metal easily reacts with air forming a black patin surface. Lanthanum metal is the prototype for the lanthanides (elements from 58 to 71). Like these, it is silvery in color and quite soft. If counted among them, Lanthanum metal is the most reactive of those and the one with the highest atomic diameter. Lanthanum salts are used in optical lenses, alloys for special applications and in some batteries. In nature, Lanthanum always occurs in compounds.
Amazing Lanthanum metal standard density cube 10x10x10mm, 99.99% pure. The sample weighs approx. 6 grams (with a tolerance of ± 0.1gram), which is the theoretical density of the Lanthanum metal itself. This cube is amazing for any science classrooms, schools, universities and collectors. Pure Lanthanum metal cube for element collection.
The sample comes under argon sealed ampoule
