Calcined aluminas are generally obtained from Bayer process gibbsite α-Al(OH) 3, thermal decomposition of which follows the transition through the generic gamma alumina phases to α-alumina (corundum), α-Al 2 O 3.Calcination of gibbsite has been done in rotary kilns for many years. Specialty calcined aluminas can also be prepared in stationary or fluid bed calciners.
