Description: Pink powder, insoluble in water, soluble in acid. Very easy to absorb moisture, can quickly absorb the moisture and Carbon dioxide should be placed in a sealed container. Uses: It is an important raw material for preparing rare earth metals and alloys by oxide electrolysis and calcium thermal reduction, Such as the oxide electrolysis method to produce metal and use its fluoride as electrolyte. In addition, rare earth fluoride is also used as an additive for steel and non-ferrous alloys to improve the performance of steel. | Description: pink powder, insoluble in water, soluble in acid.
