LANTHANUM
SPUTTERING TARGETS (La)
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: Ignites spontaneously in powdered
form. May delay blood clotting and cause liver injury.
