Stability

It reacts quickly when exposed to oxygen and water. It is heated to 150~180℃ in air to burn. The main minerals are monazite and bastnasite. Avoid contact with air, oxides, halogens, acids, and damp moisture.

Sensitive to moisture. It is quickly oxidized in the air and can ignite spontaneously. If it catches fire in the air at 150~180℃, its powder is easy to burn. It is the most active among rare earth metals. It can react with acid and can release hydrogen from water. The main oxidation state is +3, but +2 compounds can also be formed. It can be used as activator of phosphor, neutron absorber in nuclear controller, and dopant in laser.
