Abstract
Method for producing essentially pure and anhydrous rare earth metal halides by dehydration of their hydrated salts, characterized by the continuous or batch-wise feeding of hydrated rare earth halides in a fluidised bed system comprising one reactor or several reactors coupled in series; introducing a gaseous drying agent at an elevated temperature causing dehydration of hydrated rare earth halides and obtaining rare earth halides of specified maximum water content free from oxide impurities. The method may also comprise a terminal step connected to the fluidised bed system for desired water contents below 0.05 moles water per mole formula unit.
