Lutetium Ingot

MATERIAL OVERVIEW

Characteristics: Metallic luster. Soft and ductile. Reacts slowly with water, soluble in dilute acids. Difficult to isolate. Generally low toxicity. Lutetium is a silvery white metal, resisting corrosion in dry air, but not in moist air. It is the last element in the lanthanide and is traditionally counted among the rare earths. Lutetium has the highest density, melting point, and hardness of the lanthanides.

Derivation: Found with almost all other rare-earth metals, but never by itself, lutetium is very difficult to separate from other elements. Pure lutetium metal is one of the rarest and most expensive of the rare earth metals to prepare with a price about over $10,000 per kilogram, or about one-fourth that of gold. Through a process of concentrated acids, oxalation and annealing, crushed minerals produce sulfates of rare earths. Then through crystallization and ion exchange, lutetium is separated from the other rare earths.

Because of the rarity and high price, lutetium has very few commercial uses and is found as catalysts in petroleum cracking in refineries as well as used in alkylation, hydrogenation, and polymerization applications.

Hazards: Even though lutetium is regarded as having a low degree of toxicity the compounds should still be handled with care. Lutetium fluoride inhalation is dangerous and causes skin irritation. Lutetium nitrate may explode and burn once heated. Lutetium oxide powder is toxic as well if inhaled or ingested.
