Abstract:By means of atomic force microscope, the surface pattern, particle size distribution, and specific surface area of La-Ti composite oxide were studied. The compound particle surface appears as a smooth sheet, the even size of the compound ranges from 19.85nm to 25.38nm. The particle seems smooth, which erects at a height from 4.69nm to 5.88nm.The surface area ranges from 58.90nm2 to 1238.04nm2. The La-Ti composite oxide nanocrystallines enjoy a narrow and even particle size distribution and accumulate closely.
Key words: La-Ti composite oxide; nanocrystallines; surface pattern; atomic force microscope
