摘要: Spherical lanthanum aluminate powders approximately [mu]m in diameter were produced using spray pyrolysis techniques. These materials characterized by Z-ray diffractometry and scanning electron microscopy. Two intermediate products identified as oxide aluminum oxide. intermediates present varying amounts all of the aerosol-furnace-prepared reflect short residence time aerosols furnace. Samples each aerosol-furnace preparation further annealed air for 1 h at 1100 C, them converted completely to aluminate.
