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.

首先，将锻烧温度由室温提升至500℃时，球壳属非晶相皱褶状致密结构；在900℃时开始有γ-Al2O3相及些许的α-Al2O3相出现，由SEM及BET结果得知，900℃之球壳表面有许多奈米级孔洞出现；当加热至1000℃和1100℃时，球壳形成稳定相之Al2O3结构，壳层表面趋於平滑，且球壳在晶界处有微裂缝存在；由BET 结果得知，比表面积及总孔洞体积会随锻烧温度之增加，有增加之趋势。
