Lanthanum Pellets
Lanthanum Pellets are a type of pelletized material offered by Goodfellow within their range of rare earth metals. Lanthanum has a silvery-white luster and is soft, ductile and easily workable. It is paramagnetic at room temperature. Potential applications for lanthanum include use as a hydrogen storage medium and as an alloying element to improve magnesium's corrosion resistance. With its low density, metallurgical properties and chemical reactivity, lanthanum pellets have diverse uses across industrial, scientific and technological fields.
