The ultimate product of calcination is the most stable phase of alumina, corundum or -alumina. This is, however, not desirable for smelting, because -alumina is slow to dissolve in the bath (refer to Section 24). For the formation of Smelting Grade Alumina (SGA), calcination is carried out at around 950°C.
