So, by calcinatlon for 5 h, they were obtained the following results: y-Al203 amorphous was formed from Alumina(I) at 500ºC, y-Al203 crystal structure with 0,9437 A size was produced at 11OOºC, x- Al20 3 was formad by Alumina(ll) calcination at 500ºC and 850ºC , a mixing of k-Al203 and a- Al20 3 phases were formed from Alumlna(II) at 1100ºC. On the other hand, calcinating by second time y-Al203 amorphous at 850 and 1100ºC far 5 h, they were formad y-Al203 crystal structures with 0,5542 A and 0,9437 A sizes respectively, and when x- Al203 was calclnated by second time at 600 and 850ºC the sama phase of x- Al20 3 was remained, but at 11OOºC were formad a mlxing of K-Al203 and a- Al20 3 phases.
