Abstract

Abstract: The effects of thermal treatment on Cu-O/Al₂O₃, Fe-O/Al₂O₃, Cu-Fe-O/Al₂O₃ and La-Cu-Fe-O/Al₂O₃ at 750～1050℃ are studied. The changes in BET surface, average particle size in relation to the interaction between Al₂O₃ and active components are elucidated. It is found that both phase transition of γ-Al₂O₃ to α-Al₂O₃ and sintering of active components cccurred on two samples containing ferric oxides at 850℃. Such a phase transition occurred only until 950℃ for Cu-O/Al₂O₃. The effects on the reduction of phase transition temperature of γ-Al₂O₃ follow Cu-Fe>Fe>Cu. La₂O₃ raises phase transition temperature of γ-Al₂O₃ to α-Al₂O₃ and resistence sintering of active components. As detected by XRD the thermal stable LaAlO₃ is formed at 850℃. LaAlO₃ may highly disperse into the active components retarding migration and agglomeration of active components at high temperature.

Key words: aluminium oxide, lanthanum oxide, iron oxide, copper oxide, sintering phase transition
