Hollow Al_2O_3 nanoparticles were fabricated from Al nanoparticles by heating processing. Fabrication conditions of heating were examined for controlling of outer diameter, inner diameter, layer thickness, and crystal structure of hollow Al_2O_3 nanoparticles. Potential of hollow Al_2O_3 nanoparticles as low thermal conductive material was confirmed. Based on the obtained results, possibility of hollow Al_2O_3 nanoparticles was discussed for low thermal conductive materials and lightweight materials.

以Al纳米颗粒为原料，通过加热法制备了空心Al_2O_3纳米颗粒。研究了加热条件对空心Al_2O_3纳米颗粒外径、内径、层厚和晶体结构的影响。证实了空心Al_2O_3纳米颗粒作为低导热材料的潜力。在此基础上，探讨了空心Al_2O_3纳米颗粒用于低导热材料和轻质材料的可能性。
