text: This invention relates to a process which may be carried out continuously for the production of aluminum fluoride from aluminum oxide and gaseous hydrogen fluoride at an elevated temperature in a fluidised bed reactor, which process is characterised in that an aluminum oxide is reacted with hydrogen fluoride in the presence of ammonia at a temperature in the range of from 400 C. to 700 C., the aluminum fluoride thus produced is removed from the reactor, the gases produced in the reaction are condensed, ammonia is driven from the condensate, and ammonium fluoride in the condensate is precipitated in the form of ammonium cryolite by means of reactive aluminum oxide and/or hydroxide, and the thusly precipitated ammonium cryolite is introduced into the reactor.
