| Research Abstract |
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.
