Abstract
The effect of Cs+ additive on the γ-Al2O3-to-α-Al2O3 phase transition was investigated as a function of the Cs+ concentration by powder X-ray diffraction and specific surface area (SA) measurements. The addition of Cs+ increasingly retarded the γ-to-α phase transition with increasing Cs+ concentration, reading a maximum at 5 mol% addition, at which the transition temperature was increasing by about 200 °C. This Cs+ concentration corresponds to an amount of cation which would almost fully cover the surface of the γ-Al2O3 grains.
