Outline of Final Research Achievements

The thermally induced microstructure changes of alumina based nanocomposite was examined for the purpose of nanoparticles, dispersed and bared for free space, which is important for catalytic application. The modified aluminas were heated in the temperature range of 1000-1300℃, and characterized by surface area measurement, X-ray powder diffraction (XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). The solid state reaction of lanthanum oxide with matrix alumina lead to form complex oxide nanoparticles as the secondary particles of alumina. The relationship among phase development, surface structure and sintering phenomena will be discussed.
