About Lutetium

Lutetium is a chemical element discovered in the early 20th century in France and the US at approximately same time. It has got the name after the Latin word for Paris. It is a dense and shiny metal, with almost no toxicity and no importance for living organisms on our planet. It is one of the lantanides which can be found and extracted from minerals like monazites. The extraction process for lutetium is quite hard. This element is mainly used for research and its industrial applications are limited by playing a role of catalyst.
