Description: Pink powder, insoluble in water, soluble in acid. It is very easy to absorb moisture, can quickly absorb water and carbon dioxide in the air, and should be placed in a sealed container.

Application: It is an important raw material for the extraction of rare earth metals and alloys by oxide electrolysis and calcium thermal reduction, such as the extraction of metals by oxide electrolysis with its fluoride as electrolyte. In addition, rare earth fluoride is also used as an additive for steel and non-ferrous alloys to improve the properties of steel
