Abstract

A new intermediate phase called X-phase in this work has been found in the early stage of dehydration process of gibbsite to χ-alumina by powder X-ray diffraction method. The X-phase appears in the temperature range between 240°C and 350°C. The intensity of X-ray diffraction peak of the X-phase became maximum at 250°C and after that decreased gradually and disappeared approximately at 350°C for the sample heated for 11 hours.
