Lanthanum Sputtering Targets (La)

 

Lanthanum target

 

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. ESPI lanthanum targets are vacuum arc melted from ingot, rolled to the ordered thickness, and machined to the finish diameter.
