All about Samarium: Properties, Color, Uses and more... 2022

Welcome to my Samarium element data sheet page.

On this page I'll provide comprehensive data for Samarium. I hope you profit from it.

Samarium Overview

Name Origin

Named after the mineral samarskite.

Symbol

Sm (Samarium)

Description

Silvery rare earth metal.

Discovery

Discovered By: Paul Émile Lecoq de Boisbaudran
Year: 1879
Location: France

Sources

Found with other rare earths in monazite sand. The sand is often 50% rare earths by weight and 2.8% samarium.

Uses

It is used in the electronics and ceramics industries. It is easily magnetized and very difficult to demagnetize. This suggests important future applications in solid-state and superconductor technologies.

State at 20 °C

Solid
