Abstract:
In this paper phase transformations were considered that occur in the process of calcination of aluminium hydroxide, and for qualitative phase analysis low-temperature X-ray analysis was used. Two samples were used, one of chemical purity obtained under laboratory conditions and the other obtained under industrial conditions in the alumina production plant at Kidric?evo, Yugoslavia.It was determined that for both samples in the process of calcination of aluminium hydroxide identical transformations appear, and the sequence of transformations present may be shown in the following way:
