Abstract With thermal analysis (DTA/TG) the crystallisation behaviour of corundum with influence of the fluor compounds were investigated. The formation of aluminium fluoridhydroxide in the temperature range 400-600°C are observed. Through the influence of AIF3 or HF the strong exothermic effect increased and a rapid loss of mass were noticed. The particle of corundum grow more, when the exothermic effects are large. We supposed, that also these exothermic effect will be due to the decomposition of may be adsorbed AIOF gas molecules.
