Lanthanum
MATERIAL OVERVIEW
Characteristics: White, malleable, ductile metal. Oxidizes rapidly in air. Corrodes in moist air, soluble in acids, decomposes in water to lanthanum hydroxide and hydrogen. Hazards: Flammable solid. May react with water under fire conditions liberating flammable hydrogen gas.
ESPI Metals manufactures and sells high purity Lanthanum. Forms include Lanthanum ingot, Lanthanum pieces, Lanthanum rod, Lanthanum sheet, Lanthanum foil, Lanthanum powder, Lanthanum Sputtering Targets, and Lanthanum pellets. To place an order please email, call, fax or shop lanthanum online.
