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.

Capillary phenomena was studied and discussed by the scholars about 200 years ago, but the progress was slow due to the limited equipments and manufacture precision of the microchannel.In recent years, because of the rapid development of MEMS and micromachining, many applications of the capillary flow is widely developing in some modern processes, such as underfilling of flip chip, flow in microfluidic chip or biochip, and a variety of other fields.

摘要 毛细现象大约在200年前便断断续续被欧美学者所研究讨论，但由於当时微细加工受到仪器设备和制造精度的限制，因此发展极为缓慢；近年来由於微机电系统与微细加工之精进，许多具有微流道的应用设备，陆续被制作问世，加上光学显微镜与影像撷取设备的普遍，对於研究此课题的推展极有助益；且随著微生医、覆晶底胶充填与微流体系统等领域之受到重视，毛细现象导致的充填问题、驱动原理及液体流动的控制，都变得相当的重要；本研究基於如此的动机与目的，进行微流道内液体之毛细流动现象及时间的探讨。
