Abstract

Procedure for obtaining aluminum trifluoride, characterized in that it undertakes to react a compound chosen from hydrogen fluoride, ammonium fluoride and an alkali metal fluoride, with an aluminum oxide that has a residual water content of 2% at 15% by weight, a specific surface area according to BET of at least 250 m2/g and a water absorption capacity, with a relative humidity of 50%, greater than 10%, with the reaction being carried out at temperatures of 20ºC at 700ºC.
