First, from room temperature to 500oC, the shell structure is amorphous with crinkly and airtight character. The shell structure begins to change into γ-Al2O3 and α-Al2O3 at 900oC. The surface of shells shows nano-sized pores at 900oC from SEM and BET analyses. When heated to 1000oC and 1100oC, the shell forms stable α-Al2O3 structure with smooth surface. Cracks often occur at the triple grain junctions. The specific surface area and the total pore volume of the hollow spheres increase with the calcination temperature.
